Congratulations Francesco, i am happy a microcar enthusiast owning this fabulous inter now. I remember calling on the phone the seller : he told me it was his father's car, and i could hear in the phone the father saying loud "it is a messerschmitt inter" ! Funny !
Bob, yes, my father and i saw all the colours you said, and we saw too 5 dark blue inters, so perhaps was it an original colour (Gilles did not repaint it i think, except the wheels, which was a good idea i think !)
Red is only on one we saw, and we don't know if it is original or not. I am sure some day we will have mor informations on the production with this obscure car, evrything is possible : i have heard speaking about a guy who have find in a house all blue prints, some spare parts and documents about the "Helica". Considering the Helica was produced in the 20's, and that the guy found all this stuff in 2005 i think, we must be patient some more years for the Inter story !! The problem with the inter is that we don't have any family name involved in the production, so it is hard to find patents or a family house with many treasures inside !
