Excuses for late reaction on the Sipa S-70. Seems the S-70 is indeed surrounded by mysteries.
It is NOT MENTIONED in the book Les Avions Francais de 1944-1964.
The mock-up surely was at the 1946 Paris Salon (without registration?) and in my notes I found that the S-70 was finally flown in July 1949, but only briefly tested. I wonder why Sipa would put a registraton on a mock-up after they had shown it at the Salon. This could indicate that the S-70 was actually built and this then would coincide with the fact that the Observers Book of Aircraft of 1949 has the S-70 listed.
Engines of the S-70 are usually reported as two 205hp Mathis G-8R, but I have also seen reference to the 240hp Argus As-10C or even 150hp Potez 4D (Wikipedia, which seems dangerous for a 8-passenger aircraft). It seems to me the engine nacelles on the 2 photos are quite different.
On a site on model aircraft I found the registrations F-WCZA as well as F-WCZI.
So Please remove the tarpaulins, drag it out of your barn, put some air in the tires and tell us the real story on the S-70.
The only other pic I found is attached (from the Observers Book of Aircraft?)
