[PMoz99]

There were different levels of Frontflugspange, so do you know which one it is in the case in question? Info from Wikipedia follows -

Criteria for qualification[edit]
Bronze - 20 flown missions
Silver - 60 flown missions
Gold - 110 flown missions
Pennant to the Gold Front Flying Clasp
Day Fighters and Transport Units: 500 missions
Air to Ground Support Fighters: 400 missions
Bombers, Air Sea Rescue and Weather Reconnaissance: 300 missions
Reconnaissance and Night Fighters: 250 missions

Info on recon pilots/crew is particularly sparse. The only one I know of who may have flown a large number of missions apart from Badorrek is Erwin Fischer, DKG, RK, EL, but there is very little info available on him. He flew in recon units for the whole war.
Braunegg and Jochems flew about 350.
I don't have much info on Bonath - is that Dr Hans? Can you please share what you have with me?
