2-piper,

I have not PERSONALLY seen any G's which are rod cockers. Nor have I seen any 2-hook cocker H's. But if Bob Noble's recently shared theory is correct regarding Lefever serializing barrels, which were then later matched to frames...then certainly it's possible some are out there.

But from what we're thus far observed, my sense is barring out of sequence guns, G's began in the 2-hook era and H's in the single hook era.
