Thanks for the information and the link , however
I am genuinely grateful of any assistance -
I am perhaps a little
FANATICAL about Detail -
Rememer however
the devil is in the detail It is just that my Illustrated Encyclopaedia of Aircraft Issue - Typhoon
had the 4 Propeller fitted -
so anyone who knows me ( I am on E-Bay )
knows I am interested in small
detail
best wishes David
