The Maffei Regiment have a blue coat (based on the Prussian uniform) with buff facings, grey stockings and black unlined caps.
The top figure pictured is a Grenadier (note the sling on the rifle so that they can throw grenades). The ratio of Grenadiers to Muskets is about 1:20 in these regiments. The drummers wear the opposite to the infantry.
Often in battle the Grenadiers were brought together to form a composite battalion.
Senior NCOs of this regiment wore a Green coat. Pictured here is the Colour Sergeant (Standard Bearer).
