Bernard patterns, frequently acid etched, were the barrels of choice for high grade German/Austrian guns.
I've only see ONE English double with Bernard barrels; Charles Boswell courtesy of Paul Stevens. The Birmingham Proof House Trial did NOT include Bernard; I'm still not sure what "English machine-forged chequered 3 rod Damascus" was however

The question remains if the Parker "Rose Pattern" Bernard was Bernard I or Bernard II. I've been calling the prominent rose pattern Bernard II for 10 years, and could be wrong; and posted all those images so anyone can be free to decide. I couldn't find in my files what Dr. Gaddy called the Parker pattern other than Bernard.
Until we have a definitive answer from Parker literature, it might be reasonable to just call it "Rose Pattern" Bernard.
BTW: Rosa Damascena
