Heer Cavalry Signal Peronnels Trade Badge

The Signals trade badge was to be worn on the upper left sleeve as opposed to most trade badges that were to be worn on the lower right sleeve. On the Signals trade badge the appropriate branch of service color was displayed as a “blitz” Arrow.

The pre-1940 pattern Cavalry Signals trade badge made of blue/green woven cloth base with a machine embroidered blitz arrow in golden yellow rayon threads. 

Nice exampel!!
