It looks like it has been reproofed at some point. Any idea why this was necessary? Are the bores still at .729" (which is nominal) and what are the barrel thickness?

I’ll snag some calipers from work and let you know in the next couple days

Yes I noticed that too . Looks like a Birmingham Proof ( makes sense as that was where it was made ) with a London Proof over the top . From the Birmingham proof marks I think it was made between 1925–1954 . It is a lovely gun .

I’m not sure about proof marks and dates, but I read that the Dover st address was 1908-30 time frame?

There is a very helpful article by Diggory Hadoke in The Vintage Gun Journal ( an online publication ) about how to read proof marks and how they can help date when a gun was made .
