Thanks Dirk

Really very interesting!
All I have for WNr 996 is that it was the first He 51 D built and carried the registration D-IUPO.

The odd thing is then that Heinkel assigned their Versuchs nummer a bit odd, since V5 and V6 have been reported as WNr 994 and 995 respectively, but that might be date related.

The photo, as far as I can judge, of D-ILMA is that it carries a non-regular engine, which may point to it having been rebuilt at some later stage.

Does anyone else have an opinion or does everyone agree that WNr 996 was the V4 initially reg D-IUPO, rebuilt and re-registered as D-ILMA?

Cheers
Stig
