This is based on the work of Johannes Eichhorn, as discussed in my previous posting; again, many thanks to Harald Howe for the information.Differences from Friedrich's interpretation as shown in my previous template include no shoulder strap, Swedish cuffs with 3 buttons in the standard configuration, the white aiguillette and the different design of the pistol holster cover, with only one line of red lace and more pointed at the bottom.
I'll post more detailed information on the unit and its history later. In short, they were in Poland during the Pirna debacle and so were spared the forcible enlistment in the Prussian army suffered by so much of the Saxon army. They then fought with the Austrians from 1757 to the end of the war in 1763, and were present at Kolin, Moys, Torgau and Freiberg, amongst other actions.
