Do 17 related questions

[Boris Ciglic]

As my work on the book "Dornier Do 17 The Yugoslav Story" nears its end I have some questions and hope someone has the answers:

1. In 1938 pilots Schmidt-Coste and Tarnowski and mechanic Schöllkopf ferried Do 17Ka's to Yugoslavia. Does anyone know their full names. Could this Schmidt-Coste be Hptm. Walter Schmidt-Coste which later flew in ZG 76?

2. On 27 August 1941 Luftwaffe aircraft attacked Ismailia airfield in Egypt and destroyed two ex-Yugoslav Do 17Ka, then in RAF service. Any details about this attack?

3. According to GQM records (RL 2 III 1192/130/nr.8, on 11 August 1943 Do 17Z W.Nr.255320 of NASt. Kroatien suffered an accident at Butmir. Such W.Nr. seems a bit strange to me. Any opinion about it?

4. According to some documents, an Croat Do 17E had a W.Nr.4206. Did any Do 17E had such a high W.Nr.?

5. At the beginning of 1943 Germans launched "Unternehmen Weiss" against partisans in Croatia and Bosnia. All air units were subrogated to Fliegerführer Weiss, Major Bucholz. What was his full name?

6. In April 1941 Hungarian AF acquired an Yugoslav Do 17Ka and used it till 1944. In which units did it operate and what was its final destiny?

7. In early morning of 8 April 1941 Bf 110 of II./ZG 26 shot down an Yugoslav Do 17ka near Lipljan, close to Priština - Uroševac road. Any clue who the successful pilot was?
Cheers,
