Well, all kinda went to heck! Picked up the Purdey, with the understanding that if all was not well I could return for full refund. All was not well! Chambers were my first indication- looked dented from the inside, for lack of a better description- kinda lumpy. On detailed cleaning I discovered cracks on both sides of the receiver, where the top point of the locks met the frame, traveling upward towards the firing pin bolsters, or nipples. Hard to see, but one side was actually growing verdigris, which is what tipped me off.

Now, I will say the dealer had this on consignment, and I seriously doubt had any indication of the trouble, and will refund in full.

My assessment is that someone used full nitro loads in this old BP rifle, and- barely- got away with all their parts! What a huge shame!! A beautiful Purdey perfect bores, great wood, and provenance to boot, now just scrap!
