Not a 'drawing' as such John but I have a side view sketch, I could post or e-mail you a copy if it helps?
I've just made one for my car so let me know if you'd like some suggestions about how to tackle it. Otherwise Chris Gould's book 'A Guide to Building Reproduction Austin Ulsters' is probably the best reference you are going to find.
The outlet pipe is 1" OD, the tailpipe 1" ID and 1.125" OD. You'll probably need to match the inlet to your exhaust manifold.
