Thanks a lot for the info, John.
I own a 1911 Erfurt Luger. I recently bought it from a retired Nicaraguan grmy general. I wonder how he got his hands on a Luger? Lugers are not very common in Central America and specially Nicaragua. I've always wanted to own on and I think he gave me my only opportunity. He told me he also has a Luger from 1936 (didn't mention the manufacturer), but it has a lot of use. I might still buy it from him because these are the only Lugers I will be able to own (unless I buy one out of the country, which would be a hassle).
I believe you already saw my Luger thread
Thanks
