Would anyone know about when the package will arrive using registered air mail?

No, no one knows. The number won't tell you anything, but the tracking information, when it is updated, will tell you where it originates. It really does not matter what we think about the time in transit, as it will not make any difference in the actual delivery.In my opinion, it will probably arrive before Christmas - IF, and this is important - IF they actually get the item into the shipping system on Monday.

Some places ship very quickly, others take several days. We have no idea about this items.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
