Pre-war training unit codes

[Doug Stankey]

From photos and various book references I have collected a number of pre-war school unit codes. It appears that the first three digits are associated with the unit, although more than one combination can apply to a gived school, with the third digit being a variable. The last part consisting of numbers appears to be the individual aircraft identifier. Here’s what I think these unit codes amount to:

S1+A - FS (S) Posen.
S2+M - Erg (S) 1
S2+N – unit unknown.
S2+J – JFS Werneuchen.
S2+O – unit unknown.
S2+K – KFS Tutow.
S3+K – LKS Dresden
S4+K – Fl.WS (E) Krefeld.
S5+C – KFS Lechfeld.
S6+C – Fl.WS (See) Parow.
S6+D – Fl.WS (See Parow.
S6+X – unit unknown.
S7+K - KFS Fassberg.
S7+C – KFS Lechfeld.
S7+Y – FFS Halberstadt or FFS B Salzwedel.
S13+C – FFS C Wiener Neustadt.
S17+A - FAR 14.
S17+B – schule at Parndorf.
S17+M – LNS 2.

Its incomplete and somewhat confusing, but I think that it clarifies the situation a bit. I collect prewar codes and this is the pattern that emerges.
