What is a rifle with Terni printed on it that looks like a bolt action military rifle and what kind of shells does it use and what is it worth?

Werder based on the Peabody dropping block action, to replace the breech loaded Linder. The Werder remained the primary Bavarian arm until replaced by the M1871 Mauser. The Mauser Model 1871 adopted as the Gewehr 71 or Infanterie-Gewehr 71 ( I.G.Mod.71 first of many military rifles manufactured to the designs of Peter Paul and Wilhelm Mauser of the Mauser company.

During 1870-71 trials with many different rifles took place, with the "M1869 Bavarian Werder" being the Mausers' chief competitor. The Mauser was provisionally adopted at the end of 1871 pending the development of an appropriate safety. It was adopted by the German Empire excluding Bavaria.

The action was not based on its predecessor, the Dreyse needle-gun, which had been in service for 30 years. The Gewehr 71 is a conventional looking bolt action single-shot rifle using black powder cartridges. The action included only a bolt guide rib as its single locking lug, locking forward of the receiving bridge.

The now well recognized Mauser "wing" type safety lever was developed for the Gewehr 71. The cartridge was a metallic 11 × 60R bottlenecked case, holding a charge of 77 grains (5.0 g) of blackpowder, capped with a 386-grain (25.0 g) round-tipped bullet. Edit Infanteriegewehr M.71/84, Gew.

The Russo–Turkish War impressed upon European powers the importance of repeating rifles. The Mauser brothers had been improving the Gew 71 design while fulfilling contracts with Serbia. In 1881 Kaiser Wilhelm was impressed by a prototype of a Gew 71 that featured an eight round tubular magazine under the barrel, which was loaded while the action was open.

The bullet was slightly flattened, to reduce the chance of jambing or detonating of primers in the tube. There was a lever on the receiver which isolated the magazine, so that the rifle could be fired and loaded one shot at a time, keeping the magazine in reserve. Production ended in 1890 after which time the arsenals had produced nearly 950,000 rifles; however by 1888 the introduction of the French Lebel using smokeless powder and smaller diameter high velocity bullets, made this weapon obsolete.

Edit Infanteriegewehr M.88, Gew. The German Rifle Testing Commission initially tried to develop a way to convert the many Gew 71/84 rifles into having a viable smokeless powder action; however the decision was to design a completely new weapon. The Commission chose not to involve or consult the Mausers.

The result was the look of the Lebel, a Mauser-style action, Mannlicher magazine, a jacketed barrel, and a cartridge copied from the Swiss. The Gew 88 was designed to use for the 7.9 × 57J, which is considerably smaller than the 11 mm round of the Gew 71. A total of 1,675,000 Gew 88s were produced from 1889 to 1897.

Edit Infanteriegewehr M.98, Gewehr 98, Gew. Despite the choice of the Rifle Commission to not consult Mauser in the late 1880s he kept developing better rifles and improved attributes for his firearms, which he sold to other countries. By the 1890s, his improved bolt design, the introduction of a stripper clip (or charger clip) loading configuration, and a fixed box magazine impressed Belgium, Turkey, and Argentina, enough for contracts to be made.

Paul Mauser went two steps further in 1892 when he again improved the bolt design by adding an extractor that prevented double feeding from the magazine and changed the single column box magazine to a staggered five cartridge box design. The magazine now fit in the rifle without any part of it protruding in front of the trigger making it less apt to be damaged while still easily and quickly loaded from the five round stripper clips. These improvements were embodied in the Model 1893 (adopted by Spain) and then slight improvements resulted in the 1895/96 model (adopted by Sweden, Mexico, Persia, the and Orange Free State).

In 1896 Mauser changed the firing pin distance facilitating faster lock time and accuracy. Installed a cutout section in the left of the receiver perfect for a thumb to fill while loading the ammo from a charger/stripper clip. More impressively he improved the bolt again by: 1) creating vector holes for gas from a ruptured primer; 2) a shrouded bolt head that protected the shooter from a ruptured cartridge; 3) the bolt head was designed to shunt regular gas away from the face of the shooter; 4) a third bolt lug was added to keep the shooter safe if the two main bolt lugs fail; finally 5) a better designed extractor was added.

German troops were issued the rifle by 1899 and used them in the Boxer Rebellion of 1901. By 1912 the Gew 98 replaced all other rifles for the regular army and fist line reserve troops. In 1905 the Patrone S cartridge was adopted by the German army.

Whereas the previous cartridge was 7.9 × 57, a 227-grain (14.7 g) bullet that had a diameter of .318" and a round blunt end, this new cartridge, 7.92 × 57, featured a 154-grain (10.0 g) bullet of the spitzer type. The diameter was .323" which required the re-barreling of previously issued rifles including Gew 98 and Gew 88 weapons. Mauser developed some carbine models in the early 20th century, including the Kar 98 and Kar 98A (Karabiner), designed for the cavalry and other forces which needed a smaller rifle.

Although it resembled a cut-down Gew 98, with a turned-down bolt it was ungainly and had an intense recoil. But by 1908 the Kar 98AZ was introduced, which was very popular with the German forces fighting in the trenches of World War I. In post WWI Germany the government redesignated the Kar 98AZ to be the Kar 98a.

This is because in 1923 the Reichswehr created another carbine by altering old Gew 98s. Designated the Kar. 98b, they were given a turned down bolt, a side mounted sling system, and a newer style magazine follower.

The rear sight was simplified from the large rear sight and altered to a more appropriate target range of 100–2000 meters. The Kar 98b remained the same length as the Gew 98 yet was called a carbine. The Karabiner 98k "Mauser" (often abbreviated "K98k" or "Kar98k") was adopted in the mid 1930s and would be the most common infantry rifle in service within the German Army during World War II.

The design was based on developed from the Karabiner 98b, one of the carbines developed from the Model 1898 mentioned before. The K98k was first adopted by the Wehrmacht in 1935 to be their standard issue rifle, with many older versions being converted and shortened as well as the design itself entering production. In the name K98k, the first "K" stands for karabiner (carbine) and the second "k" for kurz (short).

The "98" is derived from the earlier rifle's year of adoption (1898), though the carbine itself was adopted in 1935. The K98k is often confused as being the earlier Model 98 design; however, there are notable differences between them. The easiest to spot are its shorter length, and bent, rather than straight bolt handle.

Less obvious are that it has different, simpler sights. It was intended to be a "universal rifle" for all parts of the Heer rather than having both Carbine and full length versions. The rifle has a bolt-action and uses 7.92 × 57 mm rounds (referred to as 8 mm Mauser).

It has an effective range of about 800 metres, but when fitted with a high-quality rifle scope, its range increases to 1,000 metres. The K98k has a 5 round internal magazine and is loaded from 5 round stripper clips that are inserted into a slot in front of the opened bolt and pushed into the magazine with the thumb. The empty stripper clip is then ejected from the gun when the bolt is pushed forward into position.

A trench magazine was also produced that could be attached to the bottom of the internal magazine by removing the floor plate, increasing capacity to 20 rounds, though it still required loading with 5 round stripper clips. Over 14 million of these rifles were produced by various manufacturers. However, this number includes versions of the rifle other than the K98k, such as the Czech vz-24.

From 1950 to 1965, Yugoslavia produced a near-carbon copy of the K98k called the Model 1948, which differed only from the German rifle in that it had the shorter bolt-action of the Model 1924 series of Mauser rifles. In addition, in 1953, the Spanish were manufacturing a slightly modified version, but with a straight bolt handle. By 1940, it became apparent that some form of a semi-automatic rifle, with a higher rate of fire than existing bolt-action rifle models, was necessary to improve the infantry's combat efficiency.

The Wehrmacht issued a specification to various manufacturers, and both Mauser and Walther submitted prototypes that were very similar. The Mauser design, the G41(M), failed. Only 6,673 were produced before production was halted, and of these, 1,673 were returned as unusable.

The Walther design, the G41(W), is in outward appearance not unlike the Gewehr 43. Most metal parts on this rifle were machined steel, and some rifles, especially later examples utilized the bakelite type plastic handguards. The Walther design was more successful because the designers had simply neglected the last two restrictions listed above.

These rifles, along with their G41(M) counterparts, suffered from gas system fouling problems. These problems seemed to stem from the overly complex muzzle trap system becoming excessively corroded from the use of corrosive salts in the ammunition primers, and carbon fouling. The muzzle assembly consisted of many fine parts and was difficult to keep clean, disassemble, and maintain in field conditions.

G41(W) rifles were produced at two factories, namely Walther at Zella Mehlis, and Berlin Luebecker. Varying sources put production figures between 40,000 and 145,000 units. These rifles saw a high attrition rate on the Eastern front.

In 1941, Nazi Germany invaded the Soviet Union as part of Operation Barbarossa. Just prior to the opening of hostilities the Red Army had started re-arming its infantry, replacing its older bolt-action rifles with the new semi-automatic Tokarev SVT38s and SVT40s. This proved to be somewhat of a shock to the Germans, who ramped up their semi-automatic rifle development efforts significantly.

The Tokarev used a simple gas-operated mechanism, which was soon emulated by Walther thus producing the Gewehr 43 (or G43) from the handicapped G41. The simpler mechanism of the G43 made it lighter, easier to mass produce, and far more reliable. The addition of a 10-round detachable box magazine also solved the slow reloading problem.
