1930s aluminium racing body

[mikevernon]

I've had a 1930s Riley 12/4 chassis sitting in my garden for 25 years and it's time I did something with it!
Ideally I'm looking for an aluminium racing style body for it, or somebody to build one for me at reasonable cost. Something stark and simple, without doors or windscreen but probably with a rounded tail section. I could build most of it myself, but the double curvature of a rounded tail is beyond my capabilities.
Any advice would be welcome, and if you happen to have something which might be useful sitting in your garage, please get in touch.
