Parabola, thanks for the prompt response and welcome!
My apologies for my tardy reply.

I was given the gun by a friend who has stopped shooting and it’s going to a Scottish estate where they have an established pheasant and partridge shoot.

It’s a 12 bore box lock.The barrels have been sleeved at sometime in its life but the action is tight and is in excellent condition.

As far as I can see there are no marks to give away the original owners name but it was probably a resident of Dorset or Somerset. This is because my friend bought it in Sherborne in the early 1950s.

I shall get some photos of it next week
