Leonardo's snap lock. The missing link ?

[Raf]

Hullo to all Fernandos.. wherever you may be . Sincere apologies for confusing you and thank you both for your contributions. As your probably aware I am new to this forum and am still trying to work out who everybody is.
All I was trying to do was research early snaplocks, on the assumption that such a simple intuitive idea ought to have existed at a much earlier date than the examples we have ( C1580 ) I just find it fascinating trying to imagine how these early ignition devices ; including wheelocks might have first developed and what stages they must have gone through in the development of the idea.

And Fernando ; sans K . Just for clarification. Do either of two locks you illustrate, Anselmo and Molinhas have single horizontally moving sears or sears with a prop as in wheelocks ? Difficult to see from the pictures. The relationship between these Portuguese locks , early Italian toe locks , the Aquijeta and Algerian toe locks is obviously very close and I would have thought have to be the earliest examples of a combined pan and frizen. The earliest suggested date for the Lisbon petronal (c1560) would make it roughly contemporary with the earliest vaguely dateable snaphaunces.
