One question, did you forget to include the Austrian Fliegerabwehrbataillon 3? It would be under the direct command of the Korpskommando II and was composed by:
e. Fliegerabwehrbataillon 3
1) Stabsbatterie
2) 1. Fliegerabwehrbatterie: 6 twin 35 mm ZFlAK 85, 4 20 mm FlAK 58 on AP712 Pinzgauer
3) 2. Fliegerabwehrbatterie: 6 twin 35 mm ZFlAK 85, 4 20 mm FlAK 58 on AP712 Pinzgauer
4) 3. Fliegerabwehrbatterie: 6 twin 35 mm ZFlAK 85, 4 20 mm FlAK 58 on AP712 Pinzgauer
I think that they are too many AA guns to be left aside aren't they?
