Although I have posted this on the introductions section, we are hoping there are folks on this forum who can answer a question about my cousin's Police Positive. 4 inch, 38 special, with maybe 95% original finish, holster wear with grandfather's original holster, does not appear to have been shot much, said to have been issued to him between the world wars when he was transporting mail on an airplane. Anyone here have an understanding what this is? Any speculation regarding value? I think my cousin wants to keep it but not positive. Thanks very much in advance. I have shot Colt weapons and own two right now, Love em.
