Re: Hey Jim
1st Model either a 3rd Variation (1934) or early 4th Var. (1935). Can't see the patent numbers on the cylinder - if only one: it's a 3rd, if two: it's a 4th. Firing pin is on hammer because I can't see a retaining pin in the frame under the rear sight. Serial numbers at that time crossed from the 30k to the 50k range, so the s/n doesn't nail the year. Need more data.
