I have no information about my grandfather Moishe (Moshko) Koifman.
All I have is this military notebook.
This document I think I use as a passport. So the 2 stamps are seen in Russian.
In 1936 my grandfather traded that document in the Russian consulate, I estimate that he did it to try to get the Argentine document (residence)
I don't know anything about his history until I arrived in Argentina, I think I arrived in Buenos Aires in 1911. He married my grandmother Rojl Barinstein and they had 3 children. He was a merchant, he sold underwear in Buenos Aires.
I have nothing else
