Early Spanish Musket for I.D.

[rickystl]

Hello all. Here is yet another item from a fellow collector. He believes this is a 1741 Spanish Dragoon Musket. It is iron mounted. He says the barrel was shorted slightly back in the period, and the front barrel band is missing.
I just don't have the reference material to positivly identify this musket. It certainly is a Spanish Dragoon. And, the furniture style seems to date it pre-American Revolution. Does anyone have any reference material on Spanish Military arms pre-1760? Sure would like to know what the front barrel band looked like? Thanks for any assistance. Rick.
