No problem, Norab was definetley first,
You're correct re the 'Buchon' of course, although the first to receive the Merlin engine were those provided, in kit form, from Germany, as 'G' models. Lack of DB engines lead to the Merlin fit, and the other mods followed. But, there were so many 'unofficial' changes, it' hard to know where Hispano starts an Messerschmitt ends!
