Ash Framework

[Austin-App73-77]

Would any member have any information which would help in the construction of a new complete ash body frame?
I have 2 Heavy 12/4s but nether have a body so I will have to manufacture them - drawings, patterns or just a look and measure up with a few photos would be a great help.
Ideally I would like to visit to see a part restored car with its trim removed exposing the ash frame.
Has anyone else done this in the past?
Thanks for reading this.
