Thanks for putting me right on the composition of Magnetophonband Typ  
C and L. This neatly explains why a retired German friend of mine has  
always insisted that, as a Wehrmacht radio engineer attached to a  
Soldatensender German forces station in late-1944, he used "plastic"  
tape with his Lorenz-AEG machines to record broadcasts off-air from  
Berlin.

Incidentally, being a 20-year-old swing fan he also used the  
Wehrmacht's machines and elaborate antenna array to record Glenn  
Miller's ABSIE broadcasts from England on 583kHz AM, at considerable  
personal risk. Reception was apparently rock solid, and (ironically,  
in view of the noiselessness of German recorded broadcasts) his off- 
air tapes also captured the surface noise of the original  
transcription discs.
