This may be an honour cuff title for a Fähnlein (assuming that the items were always together). These CT were sometimes authorised by the HJ Gebiet but were not sanctioned by the RJF as an official insignia. There's another on the forum somewhere (Jörg von Frundsberg).
Was this a private sale? If so, the seller may have access to the family to find out more. Worth a try I would think.
