Thank you all for the suggestions. I'll comb through Gunbroker and the other sources listed and see what I can find using the suggestions here. To be clear, the decision to go this route was not my decision. I'm just trying to help with implementation. Buying a gun for someone else is tricky business, I know. My first thought was "1301" because it seems like a nice complement to a safe full of double barrels, but oh well...
