So to confirm, this gun was owned by Arthur Gambell's son? No one seems to be talking about Poppa?? The same Arthur Gambell who managed The Cincy. Gun Club and was one
hell of a trap and pigeon shooter in the early 1900's ((1902---1908 range, roughly)? Coincidentally, a good friend of mine owns Arthur's BH live bird gun, shipped in early 1902, I believe. It's a 2-frame with 32" Titanic barrels, no safety and is needless to say, very dynamic! Unfortunately, someone replaced the original stock and gold grip cap that had his last name engraved on it.

It has to be out there somewhere. Who in his right mind would throw that away?
I will be sure to alert him on your recent acquisition. Congrats on a beautiful Parker! These two guns need to be reunited somehow, somewhere!! Hmmm, what's this? Do I feel the tingle of DGJ juices beginning to flow? Alas, who am I kidding? Parker stories are reserved solely for the Demi-Gods.
