Thank you for that gents.
The gun is a london made boxlock non ejector by Lang, built on the rare tranters patent, they don't come up often.
As it is its worth parts value of about 60.
Deactivated its worth 100 quid? and it would ruin the gun.
Sympathetically Restored and with a proof exemption i believe it's maybe 300 - 500 to a collector of patent guns perhaps.
Black powder re proof and restored perhaps worth a bit more, the blackpowder only re proof would limit the value but i would prefer the gun was shootable than, blown up by a Nitro proof.
Nitro proofed i have seen one go for 1500. Langs a reasonable maker and the gun is well fitted and finished just sadly out of proof.
I don't care about making money, this isn't a trade or a sell on or do up, its just a gun i got for me but i would rather one that i wouldn't have to cut it up re proof at least allows me to sell it to someone who might enjoy it if and when i want.
There a very small amount of pitting non rib side you really have to look to find it, i suspect its been honed ( not through the chokes though! ) not that you can tell in any way from inspecting which is probably why its out of proof.
I do mostly wood work gunsmithing - stocks, re fitting, refinishing, checkering etc. I have no experience of putting something through re proof so i thought i may as well take this as an opportunity to learn some of the skills involved the only thing i'm worried about and when these dents have been lifted in the past there is evidence in the bore.
It sounds like I'm going to have to find a smith to hands on tutor me on this.
