Welcome to the Forum. Values ( selling prices) on these guns are not high, as many 1,000s were made and only those that are still in near new condition will bring prices in the lower 4 figures. Your gun shows abuse from poor cleaning after firing, etc., as black powder is very corrosive to gun finishes. The stocks are nice and were probably "dealer" added, a common upgrade of the period. (They are ivory, not pearl) If your gun was in a good online auction, I would expect it to bring a hammer price around $400, give or take $50, assuming it's in good mechanical condition and the assembly codes on the frame, cylinder and barrel all match. ( The side plate has been off at some time past and not correctly seated when replaced. That an easy correction, however. ) Ed.
