Remember that the debate "elsewhere" was primarily on military locks of the mid 18th Century to the early 19th Century (though it also extended back to those of the late 17th C. as well) and extended to the military locks used by other European nations and the US as well. It was inspired by a European military lock (6 and 1/4 inch long lock plate?) with a separable pan that you felt may have indicated that the lock was a reconversion to flint. If you will check back there you will see that there are other sources of information that have been added since your last post. It may be true that some French civilian locks had pans forged as part of the plate or forge welded to the plate as was the primary practice in England, but not so in most French and other European armories.
Websites may help some, a few were pointed out to you, but there is little that has been found yet. Maybe someone here will be able to show us something? I hope so. For the time being, books still seem to be the main source of information on French military arms.
The long and the short of it is that Bud Siler did not invent the idea of the separable pan, it was in use long before the modern era.
As a last thought, I might add that that it seems that the separable pan was also used on most French trade guns.
