That gun shows no sign of a DelGrego restock.

To me it looks like the checkering has all been recut while attempting to keep to the original checkering pattern and style, However, the "ruptured duck" flying in the cheek panels was most probably originally a fleur de lis but poorly interpreted in recutting. The nose of the comb has also obviously been reshaped from that which would have been on a Parker of that vintage.

The reason that I form my opinion thus is that the sculpted fleur de lis drop points appear to be completely original in shape and form with the correct amount of wear to them.

Yes, it is pretty ugly, if you ask me

Originals :

I could learn to live with it.

It is only an "A" but you get the idea.

I think the gun is an upgrade.There are several of them floating around now.All seem to fall into the serial range that can't be authenticated.Back in the 70s you could buy a VHE 20 for $1000,spend $2500 on engraving,$2000 on wood,and $1500 on metalwork and then sell the gun for $25,000.There were few sources of information on Parkers back then.
A lot of big dealers upgraded guns and sold them as upgrades.After they changed hands a couple of times people thought they were original.

And there is a good reason why they cannot be authenticated...

Yep,If they can make it,they can fake it.

I doubt the wood on that Parker has ever been within 25 miles of Illion, NY.
