There were two regiments of Horse in the Piedmontese army - both with the same uniform distinguished apart only by button colour.
This is (obviously) the yellow button regiment. The white-button regiment was called Savoia.
I have shown them with three squadrons even though I have painted four. Technically they could field 5 squadrons but the north Italian state appears to have been very short on horses as no OOB seems to show more than 3 squadrons present at any engagement. I'll use the extra squadron as the basis for the Savoia regiment.
