Spitfire/GT6 hub drawings?

Spitfire/GT6 hub drawings?

I may just make new hubs in a 4x108MM pattern.
Probably 7075 aluminum.
CNC lathe and mill have to be good for more than just the day job.

Seems like these have been in use long enough that drawings should be fairly readily available.
I will have to redraw them anyway in my CAD but still simpler than having to reverse engineer them.

Anyone have drawings or a link?
