Hi Cerjak.
WOW! Another super interesting musket. Yes, appears to be a 1757 Spanish musket - but with a French lock. Sort of the reverse of the first one posted. LOL

Looks like the muzzle of the barrel had been shortened back in the period. Possibly due to muzzle damage or for civilian use. The lock plates on both the French and Spanish guns were almost interchangeable.
Two very neat muskets Cerjak. Thanks so much for posting.
Rick.
