Happy collecting, Peter
Its interesting to see that the .41 rim was still being drawn and presumably sold in april 1920 since by then it would have been very much past its normal time frame. Still it shows a market must have existed although it was a particularly weak and ineffectual calibre even in its day. So many pistols were clearly still in use even that late on. Scary really, would you trust your life to a .41 rim derringer?By the 1920s even a .38 special would have been so much more effective.
