Hi Marko,
It could very well be Erwin DAHLKE. I tried Google for DAHLKEM, but there are only 3 entries, none of which fit. I even tried DAHLHEM (74 entries) with no luck.
Unfortunalely there are 94,800 entries for DAHLKE, and I'm not scolling through all of those.
The only thing I know for sure is that neither Erwin DAHLKE nor any DAHLKEM or DAHLHEM were ever awarded the R.K.
Interesting note though; there is a Hermann DAHLKE listed as winning the RK with SS-Pz.Gren.Rgt.1 on 03 Mar. 1943. Who knows? Maybe this is our guy?
Hopefully someone out there has an answer to this problem. There are other's that I couldn't find the first name for as well.
Thanks for the effort Marko -
