Old Gun?

Where can I find the value of an 1800s JA Mortimore dbl barrel shotgun?
Been looking on line and not sure where to look.

might try www.gunsamerica.com and www.gunbroker.com and see what they're going for.....if any can be found.

Thanks Traperjohn.

sometimes typing antique gun values may give you a site or antique dealers is it flintlock or percussion

that be closer to the 1900's check on English doubles fine looking piece looks like great walnut wood

Looks like damascus barrels. Sweet lookin shooter
