Thanks for the response. Sorry to say I am not convinced by your theory regarding the digits on the fin, although Luftwaffe are full of surprises...
I cannot recall seing any such three digit numbers anywhere else except on the two He 59s stated. What other types used this system? As far as I know no author(s) has brought up such a subject before, which in itself means nothing, but I am listening, so please expand! How was it related to units??
Cheers
