En primer lugar, quiero dar las gracias a Vladimir Nikiforov, que me proporcionó una enorme cantidad de imágenes en su mayoría de Ebay. Y, por supuesto, Salvador Marín, TR Javier y Manuel Rodríguez Valverde, que ofrecieron su ayuda cuando tuve algunas cuestiones no resueltas.
First of all, my thanks go to Vladimir Nikiforov, who provided me with a tremendous amount of pictures mostly from Ebay. And of course to Salvador Marin, Javier TR and Manuel Rodriguez Valverde, who offered their help when I had some unresolved questions.
Only 32 aircraft in total were delivered to Spain, mostly the early Do 17E-1 (bombers) and Do 17F-1 (reconnaissance) variants, and late in 1938 an additional five Do 17P (photo reconnaissance).
Picture 1: Transparent view of the Dornier Do 17E-1 bomber
Picture 2: Transparent side- and upper/lower view of the E type
Picture 3, 4 & 5: Cockpit interior, dorsal blister & BMW engine of the Do 17E-1
Picture 6: Drawing with indication of differences between Do 17E and Do 17F types
Picture 7: Armament and camera installation of the Do 17F-1
Picture 8, 9: Side view comparison between Do 17E and Do 17P versions, transparent side- and upperview of the Do 17P.
Picture 10 15 : Do 17P cockpit, radio compartment, (the almost useless) ventral gun position and undercarriage details.
Picture 16 - 19: Some interesting details for the modelers (starting lorry + rear entrance door + camo and opened engine fairings) and for the period after the GCE: Ejercito del Aire painting instructions for insignia and numerals of 1940.
Remark: All sources and the captions of a lot of pictures (I have seen so far) contradict each other as far as the subtype (Do 17E or Do 17F) is mentioned. By studying the pictures of the aircraft and taking in consideration that the only visible difference between these types is the bombsight fairing of the Do 17E under the right side of the nose, I come to the following summary (while it is absolutely sure that all Do 17s including 27-1 27-4 were also used by VB.88 as precision bombers):
And now a summary of the aircraft used in Spain in sequence of their individual code.
Pictures 20 - 32:
Forced landing at Santander-Est due to damage to its hydraulic system by Nationalist fire
27-2 (PABLO 2):
Pictures 33 - 36: Very few (bad quality) pictures of 27-2 are known to me, probably because this aircraft was the very first Do 17 loss of the Legion Condor and was shot down after only two operational weeks.
The aircraft was flown by Oberleutnant Hans Sobotka, the other crew members were Otto Hofmeister and Friedrich Müller. It was shot down by Republican I-15 fighters led by Felipe del Rio Crespo, credited with seven victories. On his turn, Felipe del Rio was shot down four days later.

The remnants of the tail-unit of 27-3 after been shot down on the 18th of April 1937.
27-3 (PABLO 3):
Pictures 37 - 48:
In service with VB.88
The crash of Rudolf Jöster, former commander of the Ju 52 Pablo Gruppe, due to hydraulical problems:
Pictures 49 53: 27-3 in service with A.88 (with the insignia Das muss man haben!!): Also note the new style of lettering.
Note 27-16 Mucki in the background.
Picture 54: This picture maybe shot during the 2 months 27-3 served with 8-G-27, but that idea is only based on the appearance of the Spanish looking guys near the aircraft. On the 29th of October 1938 Luis Rambaud Goma (Jefe del Grupo) and his crew died during a mission over Salas de los Infantes.
27-4 (PABLO 4):
Pictures 55 61: 27-4 (PABLO 4) in service with VB.88
Pictures 62 - 64: 27-4 in service with A.88 (not new style of lettering and the red heart insignia with some characters under the cockpit)
Pictures 65 + 66: End of service life for 27-4? / before, while or after in service with 8-G-27 ?
27-5 (Ace of Diamonds):
Pictures 67 - 76
27-5 next to 27-1
Ace of diamonds insignia clearly visible, the A.88 insignia were added later
Another proof that the Do 17s and He 111s suffered from a lot of landing accidents on the rather crude, sandy, sometimes muddy airstrips in Spain.
Sunk in the mud
27-5 came to a bad end on the 25th of July 1937.
Pictures 77 - 79
Pictures 80 82: In service with VB.88
Pictures 83 - 85: 25-7 in service with A.88 wearing a lightning flash and the text A/88
Pictures 86 94: 25-7 in service with A.88 wearing the black cat insignia
25-7 with black cat insignia but without the red devil insignia of A.88 next to the engines.

So far Part 1, I hope you like it,
Still one unanswered question: Who can identify this aircraft from A.88 ????????????????????
All the best,
