Here's a photo (which may be of some interest to RK geeks) of Oberleutnant Merker taken soon after he received the RK on June 9, 1944. (From Band II, Die Ritterkreuztrager der Kampfflieger). It's a 3/4 ring.
This may give some credence to the idea discussed here in the past that RK distribution from the PKZ really may have been on a "first in, last out" basis from time to time.
