There is no hard and fast rule amongst the Ost-Pommern Infantry Regiments regarding uniform distinctions for musicians. It is left up to the individual Inhabers to 'tart them up a bit' as he sees fit. Some use varying amounts of lace, others reverse colors.
IR.2 'Markgraf Ludwig' makes use of much lace.
IR.4 'Steiner' Grenadier drummer
The Scots Battalion utilizes reversed colors on the coat.
