Hi new here. I just picked a 38-44 #50xxx. The gun has all the correct markings it should have for a prewar gun. Here are my questions. Did all early hd's have a "reg patient off" stamped on the hammer?. Second it has a 4in barrel. But it has the patient dates stamped on it. There the same dates as on 5in 6.5 in barrel guns. I was told 4 in guns had no stamping. If it was rebarreled w a cut dowm barrel they did a very good job. What are your thoughts. Im getting a letter to smith here soon. Thanks steve.
