Yes, that is pretty close, but most of the ones (but not all by any means)I have seen documented were full stock. But that is a great example of a Catalan butt stock, it makes the gun light and easy to handle. Another distinctive feature is that the Spanish generally used barrel bands as on this example and not pins to secure the barrel to the stock. That trigger guard is also distinctive to Catalan style firearms. Interesting forging job, I am still working to perfect mine. I am waiting for some miquelet locks to come from Kevin from Blackley, in the meantime, I have scratch made a few and like I said, I looking into having some cast, most foundries I have contacted require a minimum run of 25 so I need to make sure it will be worth doing. The advantage of miquelet locks and why the Spanish preferred them, especially for frontier/colonial service is there is very little inletting needed for lock internals, making the stock much stronger in the wrist. Actually, miquelet is a modern term, the correct name for that style of lock is llave de rastrillo or pedrenyal. Since I don't speak Spanish, I don't know what those mean.
