Morier painted all 5 mounted Hessen-Kassel troops (4 Reiter & 1 Dragoon regiments), but I found in color only Prinz Maximilian Reiter. Bleckwenn's Erbrinz/Konig Dragoner is in the part about Hessen-Kassel infantry (link).
See other materials by H. Bleckwenn about D. Morier plates with Allied army in Flanders in 1748 (link)
