Must be the same Luger, I first saw it at the Lima show. The HK in a circle is the only thing I may have found a reference to, but there should be other markings in conjunction with it or so I have read.

From another forum:
"Heinrich Krieghoff was a gun maker who was known to use a back to back “H” and “K” that looked something like the Russian letter Zhe Ж”.
