Oh wait- that was Casey "Stinky" Stengel 's favorite reply when he was managing the "Bronx Bombers" in another era- Dave, I have the 1974 ATA book "The Grand- a history of Trapshooting" by Jimmy Robinson and Jim Nichols published at Vandalia 1974- if you know the state where this gentleman shot his registered targets, I might find him in that book- worth a shot--
Chuck--The man who willed me his "modified" Parker SBT was a Class AA shot, so many shots fired in his era- no era protection most likely-. It's been years, but I think he had gunsmith Herb Orre install the release trigger, and it was on a separate floor plate- the original and the machine screws and also the solid red pad were in a cigar box that came with the shotgun when it came into my custody- I tried to get that infernal Morgan pad set for me- I also had to get used to the release trigger, back then I didn't know enough to keep it and have the original pull trigger re-installed, ditto the factory red pad.
The M12 I obtained in trade for it had a std. buttstock- it is a Pigeon Grade with the older milled rib and the "duck-billed" extension and the sandblasted receiver- it is no Parker of course, but it must have been a special order as it has a 30" Imp. Mod. choked barrel instead of the usual Full choke.
I am not a trapshot, but for many years I used it for Pass shooting Canada Geese near refuges in SW lower MI- until I obtained my two M12 3" Magnum Heavy Duck Guns. It is "retired" more or less, but like all my Winchesters- Not For Sale (not that I would even think of trying a stunt like that here)--
