I enjoy the story that we can stitch together by way of British publications and some remaining shop and sales rocords from these Gunbuilders.

I have a Purdey that features interesting chambers. When I'd contacted the maker they had some information on the commission of the build, but little to no archives on the history and development of the pinfire cartridge type and/or it's application to the build of their guns and rifles.

I was able to find out quite a bit about the customer, and from there I learned about his relationships with some other fellows who were involved in the development of cartridges for sporting and martial guns of the immediate period.
