Heinkel 70 in Spanish Civil War

[GuerraCivil]

Heinkel 70 was initially a fast passenger plane but it was converted to military purposes as He 70 F-2. The plane was used in reconaissence and bombing missions by the reconaissence squadron (Aufklärungsgruppe) A/88 of Legion Condor.

While serving Legion Condor I wonder if someone knows more about following losses regarding He 70:
- 15.6.1937 A/88 lost a plane over Miravalles, three-men crew Lt. Gottanka, Lt. Lindemann, Uo. Heerschag all KIA, was it He 70?, cause?
- 10.7.1937 over Cuatro Vientos He 70 shot down by Republican fighter, Lt. von Posser and Og. Reinhold KIA, corresponding Republican claim?
- 20.8.1937 over El Musel/Gijón He 70 shot down by flak or enemy fighter? crew parachuted

Republican (Soviet) claims vs. He 70:
- He 70 shot down on 13.12.1936 by Sergey Cherknyh (I-15), is there a confirmation by the loss records of Legion Condor?
- He 70 (mistaken as Bf 109!) shot down on 7.1.1937 by Sergey Cherknyh (I-16), is there a confirmation by the loss records of Legion Condor?

The remaining Heinkel 70´s were passed to Spanish Aviación Nacional on November 1937 and they served in the Grupo 7-G-14. Does anyone know details of the service history of He 70 in the Aviación Nacional and in the Grupo 7-G-14 during the Spanish Civil War?
