Robertson (Boss) shotgun

[LES7]

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

1.5” and 2.25” if pics aren’t clear
Between 6-7lbs I don’t have a scale with ounces

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 .

Do the early British shotguns sold by H&H, Purdey, Boss and other using WC Scott parts loose value. Or have less value. Or were they all made that way.

Why is this a “Robertson” Boss and not just a Robertson. Was it made by an Ex Boss employee?

I should probably rephrase that. I know a boss marked Shotgun is far more expensive. but what makes this robertson worth less than a boss if it’s a boss

I did a quick search. Of course many here already know. But apparently Robertson wanted to produce a more affordable SxS. So used his name instead of Boss

So was this particular gun built by John Harper ? Webley and Scott? Ilsley? Then finished by Boss ?
