Funny, I was thinkin' the exact opposite. I know Neil and he wouldn't know any better. He looked at the gun and had no CLUE what kind of lock was on it. That's why he said it was what he did.
As for Phil from Nat'l Firearms Museum, he definitely should know better and it probably just didn't dawn on him.
In their defense the miquelet, whether Spanish or Italian as it were, without elaborating on the basic differences, is an understandably overlooked action and about the last anyone would recognize the nuance of other than maybe a Scandinavian lock which almost no-one has ever even heard of in my experience...
