This is an obsolete calibred 10g, in nice damascus, obviously not nitro proofed, although when I bought this 20 years ago the guy had been using it, but found the cartridges hard to get, so we did a deal on a 12g Although this does not need a licence, I would not be happy selling it to anybody, so unless you have either a shotgun or firearm I wont sell it to you, I do not need to put it on there I just need to know your more or less sensible and a genuine collector not to be shot without re proofing first price is o.n.o.
