There is much information out there, some of it contradictory, regarding the construction of this machine. However, the chassis frame is from an Alvis Firefly.
Opinions vary a little with respect to the engine;...some say Crested Eagle, others, Speed Twenty. The gearbox seems to have general concensus as being from a Speed Twenty. Sections of the body are said to be from a Marendaz Special;...from the photographs I respectfuly suggest that this is probably the main body tub. Specifically, the scuttle area, and doors, possibly from the 13/70 model. Mr. Routledge started work in 1951, but it was not until six years later when the car was registered for the road. Extensive, but meticulously planned drilling to the chassis is what led to the sobriquet "Tea Bag".
