I don't know much about the purdey. It took forever to get bore measurements and I finally gave up on barrel wall thickness. Because of the condition of the gun, case and accessories and the tightness of the gun, I think it is barely used. From the serial number it was built in 1935. It came from an estate where I believe it just sat in its case. Once it is delivered here I'll know more. I'll ask for its records from Purdey. The Hollands are a cased pair of 12 ga Dominions, also in high condition. There is a 16 ga and a 28 ga Darne, and a run-of-the-mill 12 ga 28" Winchester 21. I only go the 21 because it was a steal.
