dear jim,
you are absolutely right; technically it is not called a RM...and it is exactly as the car pictured on page 126 of the Cosentino ABARTH GRAPHIC CAR GUIDE, i would think, after going through all litterature available, that not to many of his shape (upright lights, no radiator) have been produced. i know more or less the cars history (SWITZERLAND IS A SMALL COUNTRY) , it seems that pete ettmueller collected it late 1960 in italy at the factory and drove it back to switzerland, he told me, it was quite refreshing to drive with open windows to hear the nice sound... someone unfortunately stole the ID plate (as souvenir?) and to make room for exhaust cut out the metalsheet, so i am still doing research to have the "real" chassis number. i'd rather have no chassis plate than a fake one...:-)
looking forward to get news...
peter
