Dean , wonderful provenance. I have 77340, also a GH 16 O frame, and the engraving is no ways near as sharp and crisp as your GH. Mine was 28", but was cut to 27 before I bought it due to a dented muzzle. Still a great little gun to hunt with, I use it a lot on pheasants.

Plus what is cool about this gun is that it probably never left New England after being sold at the conclusion of the worlds fair.

Great provenance, Dean. Excuse my ZZZZs, but there were no pictures and no history before I posted my ZZZZs. I have a Columbian Exposition Parker and so do a bunch of us. A PGCA letter will tell them.

As I've often held, the history and provenance behind some of these guns is as valuable as the guns themselves. To some of us, even more so. A great treasure you have there, Dean!

My VH 12 was in the Boston Show.
