Thanks. This follows the 'logical' coding system I have seen in several secondary sources. But as stated, there does appear to be several occasions where attributions are given which do not correspond to this 'logical' coding system.

Aswell as this eBay selection of He59's with 60+_53 codes attributed to 3./KüflGr.106 at Borkum, according to Jet & Prop Foto Archiv Band 9 p. 82, 60+A53 is given as 3./KüflGr.106. Gerhard Lang (He 60 Luftwaffe Profiles,) also has the entire block of He60 codes 60+_31 as attributed to 1./KüflGr.506.

I can see no obvious reason that these sources have chosen to ignore the 'logical' coding system, unless they knew something different?

Again as stated in the first post, are there original documents which PROVE the 'logical' coding system to be correct, or is this another case of actual coding systems not always following logical conventions.
