I honestly never saw a setscrew in patillas I have owned, handled, or viewed in books, magazines, and on the internet. Perhaps because most images show only the outside of the lock and/or I wasn't paying attention. A quick review of Lavin and Neal revealed no such setscrew. So once again, you, Broadaxe, and fernando have brought interesting things to light. I love this forum.

Quite true. Many (most) of us know about the myriad forms and diffusion of the miquelet, however, to the uninitiated general public (and the NRA Museum), it is unknown and/or puzzling. That is why I created a Wikipedia page on the Miquelet Lock a couple of years ago (which could be better if I had decent images-they have strict image rules).
On another matter, on an earlier post I mentioned that the use of the patilla on scavezzos was "interesting". Poor choice of terms, it seems. By "interesting", not out of ignorance, but smug affirmation that often the scavezzos were fitted with patilla locks because they were considered more robust, reliable, and not fussy about flints; virtues a coach guard would want. That make sense?
