Hey all. My Dad inherited a sweet little relic a month or so ago. It is a swing-open derringer and the only markings that we can make out are "Union" and what seems to be "4 1/2". I'm just wondering if anyone else has heard of something like this. I'm not even sure what calibre its chambered in. I'll post a couple of pictures when I can get my Dad to send me a couple tonight. This one is a stock photo I found online that looks like his. Cheers.
