I have been going through copies of late 19th century and early 20th century 'The Sporting Goods Review & Gunmaker' magazine recently. It was the trade mag and mouthpiece of the Gunmakers Association.

Although I did not make notes, I did skim several articles, from around 1900, which discussed the Gunmakers Association deliberations concerning chamber lengths. One of their members volunteered to make a set of chamber dies to be presented to the London Proof House, for it's use. There was a photograph of the dies for several gauges in their own wooden case. I believe a Birmingham maker did the same for the Birmingham Proof House a little later on.

Sorry that the detail is fuzzy!
