Hello Michael, Sorry I forgot to include the most important file of all !!!

The photograph shows a "bump" just underneath the pilots head - I am ignoring that on my model.

PS: BurrMan,

Well spotted !
The original aircraft does show discontinuity between the prop. spinner profile and the engine cowling - my guess is that apprentices who designed and built the machine had to make do with a standard spinner off an existing DeHavilland production model.
