Not to be a pain, but this is not how it worked.
During WW1, no firearms were exported from Germany unless to a axis power. Some guns would have been brought back by a GI injured and I imagine some shipped home before the end of the war in 1918. But most came to the USA after 1919 and during occupation. But tens of thousands were still in use and hidden in germany and used through the Weimar era and during the nazi era.
