Prices are often different in various places around the country, and to be close one has to know exactly what the gun is. This usually requires a model number and a serial number too. Unless it is a very early gun the model number (36) will be marked on the side of the frame under the barrel. To see and read it you will have to swing the cylinder out first. This number is often followed with a dash and a second number, as in (36-3) Both are important to know. The serial number may be stamped in the same place, but it’s more likely on the bottom of the butt. It may just be a number, or letters may be part of it. Be sure to get it all.
In the condition you describe the gun itself is probably worth around $250.00, give or take $25.00. If the pearl grips are real they could be worth another $75.00 to $150.00, depending on exactly what they are and who made them – if the maker can be identified. While these grips are very flashy they aren’t much good for shooting, and for that purpose you may want to replace them.
Model 36 revolvers with three inch barrels are far less common then the more popular 1 7/8 inch version. However for most purposes I prefer the longer length. Nickel finish is also scarce, so the gun may become a sought after collectable down the line.
