It's probably way too late now, but do you know about Parkerizing? It's a rustproofing process of very old school which I learned about from old Harleys. I never used it but it can be done at home. Basically, you cook oil into the metal parts with heat and electrolysis. I think. I tried to look it up in some of my old books with limited success. I tried to scan some info from a book I have with no success. The internet only talks about it for guns. A lot of old machinery has it done, it creates a flattish black finish--like cooked oil. I probably have the details wrong, but it is a legitimate and authentic finish for small parts like you are dealing with now and would not be too out of place on a project like yours.
Plus I think it just the kind of thing you would like!
