I went to one of the LGS's here Monday and they had a few new guns on consignment. One of them is what I think is a .32 Regulation Police (prewar). Please inform me if I am wrong, but it seems to fit the description in the book; serial #5264XX is at the end of right range and it has the notched round grip frame with the square butt grips. It also has "June 5, 1917" on the butt of the grip. It has the 4-1/4" barrel stamped ".32 Long Ctg." and barrel head extractor knob and is in really nice shape. The price was great also. Next I will attempt to load some pictures. Wish me luck.
