Yes... especially if the restoration work is not declared up front.

Some things you have to do... like removing that deadly green gunk on fittings. If you don't, it will eat away at the metal until is is gone.

But, replacing parts or repainting or whatever is a no-no to most collectors.

Sorta like the gun collectors?
