Thanks Tony - The Italian MM system was adopted by the Germans on all Italian aircraft used by them. In my previous text I was referring to the majority of the other Foreign types used by the Germans who continued to use the original maker's c/n numbers. Sometimes when the production of Foreign types were carried on by the Germans they applied their own W/Nr often named as the RLM number alongside the MM number. This applied to the Savoia SM 82 and I have seen this system on the Dutch built Do 24s.
I have not seen most of the HW 5 documents but thanks for letting me know.
