Interesting. Thanks, Bonanza. The boxlock .400 on Cabela's site is No. 15044, Leonard number is 83? (the tool struck at an angle and the last digit is illegible). The buyer has it at J. J. 's now, waiting on a report. This was the first 3-digit gun Rusty and I had seen. The .470 boxlock at H&H is No. 15153 and has Leonard No. 1962. From the Leonard numbers on Jeffery rifles that I have rough dates for, I think the .470 is from about 1914. Your gun is 111/1124 guns earlier, so I think it has to be a pretty early gun, though certainly not earlier than 1905.
