I read this article last night. I had a similar experience. Went to a gem and mineral show in AZ about 20 years ago.. saw a stock sticking out from behind a door. I asked the guy what it was.. said he wasn't a gun guy but had traded some gems for it and jut had it sitting there.. it was an old double shotgun with a WELLS FARGO logo affixed to it .. ended up walking out with it as well.. had it sent to a place out east to have it authenticated... result stated they were 94% certain it was a truly used as a stagecoach shotgun for Wells Fargo in the late 1800's to early 1900's..
