Unusual lock for ID

[celtan]

That makes yours even rarer. I've heard of the Madrid Locks, a variation of the flintlock "patilla" (span. for small-leg/side-burn) lock, but have never seen one. There's no data of their use beyond the peninsula.

Congrats!

Although this 'infrequent' (his term) variant was confined to the XVIII century, this example of mine is of course a later specimen and, the interior mechanism that retracts the cocking studs when pulling the trigger, looks like a singular solution to me.
Indeed the design of the lock plate is typical of flintlocks; due to that, the first thing i did when i saw this gun was searching for traces of previous flintlock devices, but in fact the plate metal is intact; despite its 'suspicious' aspect, it was indeed born for percussion.
