friends,

would you be able to decipher the code ID tag Nr. 3717 ?? Could it be Gr.KFS 2 or KBS 2 Hörsching or FFS A 72 ?? Or something else, but definitely a Luftwaffe unit.
Would you know where to look for other four digit codes ?
There are only about 5 four digit codes in Jean Hoidal's book Deutsche Erkennungsmarken.

Thanks, Jan
