Also, I stubbled across this, which is a modeling, article on the Defiant which might be of some help.

On the Defiant turret issue it looks Mike and Tom were correct. I have done some more research and it appears that Boulton Paul submitted the design incorporating a the French SAMM turret, but the production machines used the A. Mk IID turret.
Thanks all for all the info on 109 noses and Mike that's a fine looking Emil.
Cheers
