I have long said that you can't sell a repro for more than the price of the originals, but it might be that folks think the repro will not be on the market long and will be a collector's item in itself.
FWIW, I have one of those Parkerized pistols and it is much better made than that one. The finish is matte, but very smooth, and of course it is in the regular serial number range. They didn't even quite get the shape right.
I take it "GOP" means "General Officers Pistol" (or is it intended to keep Democrats from buying it?), but most of those pistols went to less exalted folks, including doctors and nurses, who were allowed to carry defensive pistols for the protection of themselves and their patients.
