Hi. I'm trying to get an idea on the value of this Model 11/2 1st issue tip-up revolver SN# 354. Bluing looks good & original (for a 151 yo) , grips look original with good finish, no cracks or scratches. There's a bit of play in the barrel though. No paperwork or box, this came to me from my Grandfather (died: 1961) so I've got little oral history on it. Wondering if it would be worth getting factory paperwork on this, and maybe a ballpark estimate of value. Most "dealers" locally give me guesstimates from $50-$100 range, but I find that suspect. Thanks in advance for any help you can give.
