Doug did two guns for me about 18 years ago, when his shop foreman was named Parker. The first, a GHE, has no stamp but on the second, about 6 months later, an LC Smith Trap Grade, he was offering a 10% discount in exchange for putting a Dt stamp on the watertable. I bit, and have no regrets. He did a complete restoration, wood, metal, engraving, TIG welding the lug to bring it on face, for $2150, net of the $250 discount. I suspect the same job today would go for three times that much. I'll post a picture of the stamp when I get a chance.

The areas I circled in black do not look like the result of a heat treatment, they do no coincide with section changes and are too sharply defined. I am not sure if this is part of what Brad was alluding to.
There are similar, nondescript spots on the opposite side, whose edges are equally sharp, and unrelated to section thickness changes.
Nonetheless, the gun is very pleasant to look at,

I wouldn't be concerned on who did it I know the birds won't care. It's a nice gun just enjoy it, congratulations.

Edgar,
I always enjoy your informative posts. Please keep them coming! But you and some others are overthinking the colors on this gun. The colors are definitely, positively and without a doubt all genuine bone charcoal case colors. Sure, they came out a little heavy on the yellows for a Parker, but they are genuine colors none the less. The variations that have been analyzed on this thread are most likely areas where a protective coat of lacquer or varnish has worn off, making it look like a variation in surface thickness. In fact, if you look at the right breach ball, you can clearly see a splotch of remaining lacquer or varnish. A disassembly and acetone soak would remove all of those fragments and not harm the colors at all.
Happy new year everyone!

I agree with Edgar - something just doesn't look right in the area he highlighted. At the same time, the gun does look good. I don't get all that picky, especially when it isn't mine.

I wish my Del Grego refinished VH 410 looked that good.

If you get a gun colored by Delgrego now, it will look much closer. Turnbull is coloring guns for them now. And Doug told me that himself.

It's a smallbore Parker, what's not to like. I'd be quite happy with that in my safe Bob. Nice gun.
