Here's a Blood Order Medal I picked up in Europe back in 1972.
It was issued to:
Hartz, Herbert v., federation upper country, ii-battalion, 8.Minenwerfer-Kompanie, blood medal Nr.250 to 9.11.1933. Wish I had the ribbon for it but the medal is rare enough. each medal was individually stamped with a number and recorded as to which recipient received which medal. His is #250.
