Unusually-styled - and I deem early- ie. pre-war-period - WH (Luftwaffe) 'Armwinkel' (or: arm-chevron): 'Hauptgefreiter'

This is an attractive - and unusually styled! - example of a WH (Luftwaffe) 'Armwinkel' (or: arm-chevron) as was executed onto a bluish-grey-coloured- and/or woolen-based (and nicely backed!) background as was specifically intended for usage by a soldier with the (unusually encountered!) rank of a: 'Hauptgefreiter' (ie. senior-private) and that comes in an overall nice- (and I deem probably issued- albeit I deem never tunic-attached-), condition. The chevron is neatly executed and shows a single stripe of (3-pieced!) silver-coloured, LW-pattern NCO-braid attached. The patch is, moreover, nicely backed with a piece of white-coloured, linnen-based material (as can be seen on the pictures). It sounds maybe strange but these 'simple' Luftwaffe-related rank-insignia are quite hard to encounter. Simply an attractive WH (LW) rank-badge that will be hard to be upgraded!
