Franck,
Good catch. No question that the bell insignia was used by 2./JG3 into the late-winter or early spring of 1940. I have an excellent photo of that in the EoE photo DB on the cowling of a 1940-camouflaged a/c, which I will post here. Note that the trees appear to be leafing out in the background, so this may indicate that this insignia may have continued in use until April.

Regarding the crash photo that you posted, my notes say I won that photo on eBay, but the scan in the DB is from the auction (same as you posted) and not from the original. Got to see what happened to the original. Anyway, I think that this is an excellent match up to the March 16, 1940, 2./JG3 crash by Uffz Hering. We've already completed a color profile for the Sta Kap, Hptm Heinz Gärtner, R1+ with the Sudenten Bell insignia. This represents 2./JG3 for Sept., 1939, and the Hering a/c might well make an excellent candidate for the Phoney War/Sitzkrieg profile. I believe that this is "Red 12." Certainly by the beginning of the WC/FC the unit was using the I Gr Tazelwurm insignia on all its a/c.
In the EoE DB we currently carry the Hering incident as:
16 March 1940: I./JG3 Messerschmitt Bf109E. Hit an obstacle on landing at Bonn-Hangelar. (Ff) Uffz
[ ] Hering unhurt. Aircraft 95% damaged - write-off.
Can anyone provide other views of this crash and/or the first name of Uffz Hering, so that we can complete the info on this incident?
Good match Franck. Your efforts are appreciated.
