It will be a handy little gun. Being proofed for black powder it may well have 2 inch chambers as they were standard until around 1913. No great problem if you load for it. 1 Dram of powder to 3/8th. ounce of shot with card and felt wads and a roll crimp works fine. The early ones were never meant as sporting guns but as guns for people collecting specimens for taxidermy. I have had a couple lengthened to 2 1/2" in the past and re-proofed for nitro. Lagopus.....
