Can you suggest what to do with an ancient Aviakit leather helmet and goggles?
They belonged to my father who would have been 86 this year. He built and raced go-karts, rode and repaired motorbikes (and cars) as well as doing his day job. The helmet is old and dirty and has ancient goggles attached to it. I am reluctant to clean it up in case in doing so, I destroy some clue to its history.
I would ideally like to sell it to someone who will restore it, or give it to a museum.
