Of course, but they don't contain very much information, I'm afraid.
" Merckle M 68:
This type is under development now. It will be powered by a German turbine engine with 650 PSe
(shaft hp) and be used for special purposes. Technical data weren’t released still yet. Flight test is
expected to start during summer 1961
Merckle M 69:
This twin-seat helicopter is under development, too. A prototype already under construction. It’s a
very simple construction and is mainly intended to be used for pilots training and sports flying. No
further details were released still yet."
I'm not qute sure, what is meant with "special purposes", I would rather think of something like
light crane/ logging, or civil surveyance, than a military use.
