Saxons SYW: Rochow Fusiliers

At first sight this regiment does not look Saxon at all but it was raised as a Fusilier regiment and by that original description it's job was to protect the artillery. By the SYW it was just another line regiment and had lost it's previous specific role. But if you look at the uniform of the Saxon artillery you will see that this regiment had essentially the same uniform with the exception that the artillery had gold/brass buttons and Rochow probably had silver/pewter ones.

There is confusion about the button colour but I stick to the theory that this regiment had white buttons to distinguish it from the artillery.
