Dean the following is my original post in which I stated:
Garry I looked at 3 letters on guns with a trap comb and all 3 mention the grip and the "trap modified forend" but nothing on the actual comb. Dang the luck !

Oops... I missed that Randy - Sorry

Garry, after some research this is what I found on "ball grips"...Couldn't just pass this up. Sent to me by a friend.

But do you have a research letter??

No research letter as the dates don't coincide with known serializations. Only more images.

I have two of what I consider true ‘ball grip’ guns, both Lifters, both D or equivalend ‘dollar quality’ guns, one a 10 gauge and one a 16.

Apparently the Parker nomenclature changed over time. It makes sense that it would.

Garry as you do not seem to be getting a lot of hits on this topic have you considered perusing through some Parker catalogs to see if there might be some nomenclature within them specific to comb terminology. I know that some of them mention the Monte Carlo and Cheek Piece options so you never know.

Thanks, Randy, that’s a great idea. It will give me a good indoor quest on a cold day (like we’re having today).

I can’t believe that the honorable Bill M. doesn’t have a letter or three that would help out. (Bill, where are you?)

I looked thru my copies of Parker catalogs and prior to the 1910 catalog, Parker only listed straight or pistol grip. The pistol grip would include capped pistol grips, round knob pistol grips, and ball grips. Ball grips were on the early hammer guns and looked like a bulb. Parker did use the term "ball" on their later .410 guns. Starting with the 1910 catalog, they used the terms straight, pistol grip (includes both CPG and round), 1/2 pistol grip, and Monte Carlo.
