Lacking infinite funds to develop this new technology, he resorted to using fillers, heat, and drying oils to create oil and fuel tight frame members, but his chassis were still prone to cracks and breakage in use, and the products of his inspiration, the MGC motorcycle (Marcel Giuget et Cie.)

MGC made roadsters and a very few racers, an example of which is shown here, fresh from restoration. The racing 250cc JAP twin-port engine is mated to a Burman 3-speed gearbox, the front forks are Bramptons, and the brakes are effective-looking 7" items with turned fins on the drums. Best of all, it's registered for the road.

When the MGC was introduced, Motor Cycling (July 27, 1929) commented;
"A curious machine has just been put on the market...The frame,engine cradle, carrier and even the petrol tank on this machine are made in tough aluminum alloy known as Alpax [made by Lightalloys of London]... lighter than aluminum [yet is] enormously stronger, whether in tension or compression.

There are two main members to the frame. The top member includes the petrol reservoir in one casting and the tank suggests a rather over-sized ostrich egg, which someone has plated and polished. On top of the tank is a particularly neat instrument-board, whilst the gear-change quadrant is mounted on the side of the casting.
The bottom member of the frame, as may be seen from our photograph, constitutes a very robust cradle for the engine, the latter being either a 350cc or 500cc JAP [which also contains the oil tank].
Upper and lower frame members are joined by two pairs of what appear to be steel drop forgings.

This machine is an extremely rare racing model from 1932, one of only two known (the other being in the collection of Bernard Salvat, and shown in the 'Art of the Motorcycle' Guggenheim show).
