His name is Ramon.
He was very polite and responsive to my requests.
However - bottom line is that there is no provenance, other than his claim it came out of an old Gettysburg collection.
Charlie - there's no reason not to ask for proof of the provenance, I don't know of any legitimate seller who would be offended.
And there is revwarcannonballs, who will come up with any documentation you can possibly request. He is one of the (if not THE) biggest crooks on eBay. He'll give you family letters, museum (all closed now) bills of sale, even make up stories about his own ancestors, to ID almost every item he sells. He'll "doctor up" projectiles, and he used to have a seemingly endless supply of Bristol made replica Confederate flags.
