Hi people, i am a new member to this forum so sort of still trying to find my way around it!

Anyway i am about to purchase a deactivated ww2 Thompson M1A1 in a couple of days, however i am unsure in how to maintain it in order to keep it in its original condition ( e.g. Prevent rusting!)?
I would appreciate any advice and help and look forward to talking to ya all!

Regards
James
