Morane Saulnier MS.660/661

Looking through my unfinished tasks at the end of the year, there’s one, I
would like to ask for help:
The MS.660 (nowadays it would be called an ultra-light, I think) was intended
to be sold just in the form of plans, or pre-fabricated for self-construction.
The prototype flew for the first time on the 17th of February 1946, powered
by a Train 4E engine with 50 hp.The second prototype, with more rounded
shapes, a different landing gear and 60 hp Aster engine, was further modified
later to become the MS.662. What I’m desperatly looking for, are photos or
drawings, than those shown below, especially of the 661/662. The artist
impression may have been influenced more by the MS.661, than by the 660,
could be indicated by the landing gear and the single strut supporting the
wing, but maybe, the artist just put a little bit too much art into it ..
I couldn’t even find another aircraft fitted with an Aster engine, which could
give at least a rough pattern for the nose section.
Every bit of help would be very appreciated, thanks in advance !
