Now that is a very nice hammergun!
My own first Purdey is a percussion 14 gauge. "The book" describes sent out for sale on Dec. 1, 1844. A friend suggested I should contact Purdey to let them know the gun is still in existance. They responded with:
Dear Mr. Butler

My question is - is investing in that provenance worth pursuing?
Here's the gun. Has obviously been redone along with the case but is very nice just the same.
