In 2007, I purchased an A1S Parker Reproduction "In the white" from Tony Galazan. Tony was kind and allowed me to buy the sample gun that he used in his advertisements.
I live a "stones throw" from a world class engraver named Lisa Tomlin. She designed the engraving for this gun in a traditional Parker style with SPRING GOBBLER SEASON IN VIRGINIA as the theme in the engraved scenes. As always, Lisa did a masterful job which involved 200 hours of work ( 2barrel set, 20 ga, english grip, sst and a beavertail foearm ).
I had Turnbull do the metal work and case color. I also requested that Doug take the existing stamp off the top barrel rib inscription and replace it with THE PARKER GUN designed stamp. The stamp was designed with Parker "arrows" on both sides.
Brian, I expect that stamp is what you saw at Doug's shop.
I hope I did not get in trouble!!
