The Pope 22 LR that I have is an S&W, it's marked H. M. Pope on top of the barrel and there are two fired targets with it signed by H. M. Pope. Sept. 13, 1913, one is a 55 Shot target and the other is a 10 shot target. The targets are numbered
4428-688. It's been awhile since I shot it but I don't think the barrel is marked with any code, twist rate, or Mfg. date.
