Are you sure you want to go there? I found Nobody & Son (Trade gun of Keeper grade) Bath Street Birmingham 28" 1/2-1/4 chokes 2&3/4" 1&1/4oz proof for $500.
And, what have you got for $500?
Answer, . . . . a gun that, when it breaks, will cost you more to be repaired than you paid for it. No thanks.
Parts are readily available for 311s.
I would take the Brit boxlock for 500$ myself, when they both work, one will be a decent handling gun, the other, not so much.
Given the choice, for $500 equivalent , if I was more concerned with repair bills I’d opt for an AYA boxlock in the best condition that I could find at that price point. They’re invariably a nice handling gun and benefit from disc set strikers, chopper lump barrels and replaceable hinge pins even in the cheapest number 3 and Yeoman models. If I was willing to gamble on the repair aspect I’d find an English boxlock non ejector 30 inch barrelled gun that fitted me well enough and had a balance that set it apart from the average more modern machine made gun. My Greener,Webley and Williamson boxlocks have never needed costly repairs in my ownership and all could be bought for not much more than £500 each.
For example on the uk guntrader site there’s a Greener Empire for sale described as in great condition for £450 that’s where I’d spend my money.
Edit to add £450 Greener Empire now sold ,one described as “in excellent condition” at £565. A search on Guntrader for side by sides filtered price £400 to £600 shows some good options.
