I have a question please.
In the antique firearms collection world, if you acquire a 100 year old piece and then proceed to very thoroughly clean it, by using cleaners or chemicals to remove every bit of grime, grease, rust spots, etc. , then you have ruined the value of the piece (cut it value down to about 40%) because you have removed the 100 years of built-up "patina." (Antique folks love patina.)
Most of the tinplate cars at the flea market definitely have such a "patina", and often an unsightly one. (And no joke, some of them smell pretty bad.)
What is the protocol here please. If I buy one, should I scrub off the patina or not? (Some of those rust spots are raised rust.)
Thanks for all information.
