High Standard 22 Mag. Derringer & rig.
Here are some pictures of one of the firearms I inherited when my mother passed away. The derringer has an ungodly trigger pull and I don't know how she ever fired it. I guess adrenaline counts for something. The picture of the holster came out darker than it is. If anyone is looking for a holster like this it was made by "Hunter" and the serial number is either 1100 55 or 100 55. I can't be sure.
