The family asked me to find out about this old revolver, test it for proper fun tioning, etc. Although it's not for sale, I am curious about its value, and we might need to know that for insurance purposes. Pre-war S&W k-frame round butt .38 spl with factory 2" barrel. I hear these guns referred to as the M&P (military and police model) but also as the Model of 1905, fourth change. it's what later became numbered as the marvel 10 but this one based on the serial number probably shipped out of the Smith and Wesson factory sometime in the 1930s at the peak of the Great Depression. The hammer has been bobbed. This is not a true double action only revolver. You can still cawk the hammer into single action mode if you can get a grip on it. Serial number 6089XX. S&W prewar revolver collectors and experts, what do ya think?
