I have a .22 short revolver that I got from a great uncle 30+ years ago. It is branded "Little Joker" by J.M. Marlin New Haven Conn U.S.A. According to what little information that I can find, it is one of about 1,100 manufactured between 1871-1873. It is a single action repeater with nickel plated brass frame and blued 2-1/4" barrel and rosewood grips. The serial number seems to make it one of the last ones manufactured. The finish and grips are in good shape. It has a center pin that is released by a push button to extract the cylinder or to empty and reload. About the only source of information that I can find is at http://books.google.com/books?id=iR...sig=ze0CCgl1Q44vhm-TnKTvBjX4t68#PRA2-PA119,M1 I want to clean it and oil it up, but I can not get the cylinder pin to come out easily. I hate to use pliers on it. Everything works as it should, but I just can't seem to get the pin out with my fingers. Any suggestions on getting it apart and cleaning it without hurting anything? Any idea on value? Thanks for any help.
