Just been reading some stuff which concerned the HJ Einsatzgefolgschaften and the DJ Einsatzfähnlein. These were ordered by Stabsführer Lauterbacher in 1938 in Berlin, Munich, Hamburg and Dortmund to act as honour guards for large parades/visits. Anyway, it's mentioned in the order that these units were authorised to have honour names and that a CT was permitted for wear. This Frundsberg CT may therefore be such an item. The units only consisted of 120 personnel so I wouldn't have thought that the RZM would have been involved in the production of such a small run so perhaps we also have an explanation for the home-made appearance too.
