This is Walther Gerhold(1921-2013) He was an RKT because he piloted a one-man sub all by himself, and sunk the British Frigate "Trollope". In the foto above he is receiving the RK from Admiral Hellmuth Heye. In the foto to the left is Walt in the one-man sub, which is attached to a Torpedo. Looks like fun (not) These fotos are very poor quality xerox copies of a real foto, but the signature is genuine & real. You get BOTH of these fotos for $19.95! CLICK THE IMAGES TO SEE THEM BETTER.
