4 speed gearbox advice needed.

[pauly1]

Does anyone know of a period (pre1940) 4 speed gearbox that would be suitable for a model a Ford race car. It needs to be quite compact as it’s a single seater with limited room. Length isn’t too much of an issue but it can’t be too much wider than a standard model a box. A AA gearbox isn’t any good as 1st will be too short.
