Serialization help please

[Pay Dirt]

Serial #190332 12 gauge DHE
I'm curious as to what the book says regarding configuration?

Another question, Barrel wall thickness was measured at .036 and .052. What do you make of the difference in thickness?
This attractive gun is a Del Greggo restoration. Any ideas as to value?
Images to follow.

Thank you as always,
Bobby

Bobby: Your Parker is not in "The Book". You should check on the PGCA web site & see if there is info available on your gun. If so spend $40.00 (if you are a member $60.00 if not) and get a letter. Any 12 bore DHE should be worth getting a letter. It sounds like your DHE has had one barrel honed. A Del Grego restored 12 bore DHE should be worth $5,000 - $7,000 in my humble opinion.

Best Regards, George
