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 .

Those barrels are perfect . It is a lovely gun. With regard to the 2 sets of proof marks I have noticed a lot of older guns ( and rifles) sold through Holts in the UK have been reproofed - generally in London . I imagine this is to assure buyers that the firearm is safe . It would originally have Birmingham proofs ( likely action and barrels supplied by Scott ) and then finished and sold by Robertson via the Boss London outlet . Boxlock guns made in Birmingham were sold by Boss , H&H and Purdey . They were all good guns and fairly rare .

Would you sell some of the 2 1/2 shells ?

 

[Wyfox]

Couple questions.
Whats the barrel wall thickness at the muzzle? Chokes? Weight? Drop at comb and heel?

I'm having a hard time making out the barrel wall thickness, .0755"?? That would be extremely thick for an english gun even if it had been sleeved. Normal would be .020"-.030" on original barrels.

I meant choke restrictions for the barrels not choke tubes.
