Here are some more images that might help. One local dealer suggested that the extra checkering would have been an added special order item, would that make sense? I will get a few more that may help more.

I tried to "reply" and add more images, but alas something did not work...will try again

You'll never know about the checkering on the cheeks unless you order a PGCA Research Letter... and that may not even answer your question.
I will say that it doesn't look like factory checkering.

Again, a better picture might be more definitive.

Harry, thanks for the response. I had not seen anything that would have explained the "D", so appreciate the insight. Not sure I would ever try to shoot it, but happy to pass along the feedback to Uncle. Hhe is 94 and not sure he has any intent to fire it, about was very interested to know about the gun his father left him years ago.

Sorry, but it seems that quick responses will not allow for the attachment of images...this is the most archaic posting forum I have ever worked with...

George, don't use the Quick Reply window if you are wanting to post a picture or other advanced feature. Use the NEW REPLY button just above the Quick Reply box. See the blue circled icon in my image below.
From there you can add pictures again just as you did before.

Seen quite a few D grade guns with checkered cheeks, including my little 1906 0frame DHE 16. Had alot of knowledgeable people look at it with out spotting a repair. Nice old Parker, George. Looks to be in good shape, how do the inside bores look, pitted or in good shape?

George,

Sherman Bell wrote a series of articles for Double Gun Journal titled "Finding Out For Myself." The short and long of it is he debunked the dangers of Damascus. Standard 12 gauge loads are limited in pressure to about 12,000 psi. He took two Parkers both made in 1900. One was Damascus the other Vulcan Steel and both were on #2 frames. Each failed at the same spot at about 31,500 psi.

Some gunsmiths would hide repair to stocks with checkering. I have several with repairs in that area sans checkering.

Harry

More Images...
 

Appreciate all the feedback...here are few more images, and have a few more to follow...I will also try to get a shot of the barrels, but they looked bright and shinny

I have uploaded several more images, but they do not seem to be presented. Is there a limit to the total number of images that I can be place in a thread?
