Thanks Dean. I sure would like to see a 28ga. DHE "P" gun. I've thought that I've been paying attention ever since the dark ages, but obviously not. If you or others should come across one of these so-called prototypes in any other gauge other than a 20, please let us know.
In the 2nd part of your response above, is the gun stamped "P 20-0209" or simply "P-209"? (It's been reported they've been stamped both ways.) In either case, one would logically have to believe that it was the 209th 20ga. produced. But, in that wonderful SHOOTING SPORTSMAN MAGAZINE article written by David Trevallion entitled
"A PARKER REPRODUCTION COLLECTION - A visual feast of rare smallbores" (
https://shootingsportsman.com/parker...tion-shotguns/ ) Trevallion reported in that article that there were only 41 .410 Repros ever produced. If that information is 100% accurate, it leaves me scratching my head to explain the pic below.
