Kriegsmarine KM medic patch?

[Ulsterman]

Amidst a pile of old Boy scout patches, some WW2 US patches, many, many band and cheerleading patches I found this. It does not glow. Methinks it would make a "so long, farewell out there on the sunny beach Paul R". present.

Question is, is it pre-1945 of Bundeswehr? I know not much about german cloth.

Thanks-

S-s-s-s-snakie's upside down. Hard to tell from the wear, but either late war army, maybe naval land forces, or police-- Feldgrau.
