There are more than a few uncommonly heavy Parkers out there. #3 frame 16s, #6 frame 10s and 12s for example. More than a few years ago, I believe it was Littlejohn's Auction that sold a collection containing many extra heavy large frame small bore Parkers. I would be interested in seeing the catalog for that auction. Measure the exact distance between firing pins on the GH. A #1 frame would be 1 1/16" spacing, a #1 1/2 or #2 frame gun would be 1 1/8" spacing.
