Sorry Stuart, you are quite right, what I meant to say was Quadricycle class vehicles. I have always wondered about the alleged 125 Inter, was it really sold by the factory as a 125 or was it converted later. The dates you quote are also significant because Inter production ceased in 1956 and if the sans permis thingy started in 57 it was all too late for Inters to sign up to sans permis anyway unless it is one of the cars that were rumoured to have been assembled in later years from left over parts. I have never seen any brochures offering the Inter in both 175 and 125 guise. If you are right it makes the plot that much more interesting, do you have something in writing that I have missed to substantiate this? Cheers, Bob
