Hello all, I may have the opportunity to buy an 1871 Purdey hammer gun in original case with ivory tools etc. It is Damascus barreled and appears in very good condition and it has provenance. My question is this, I have yet to examine the gun myself but as it is not nitro proofed I think I would be taking a risk shooting it with modern 2 1/2" loads. If I send it to be proofed and it fails, money is gone frown However I could get Teague to line the barrels so then no problems. What would this do to the value of the gun though ? I would appreciate input from you chaps in the trade on this, Dig etc, thx ijn advance, Mike
