Just a curious finding: the JG 26 (Luftwaffe) ace Hans Krug had in his plane the motto of García Morato:
Vista, suerte y al toro which is a somewhat direct reference to SCW - just a coincidence or a tiny possiblity that Hans Krug = Hannes Krug = Johannes Krug?
Edit: Johann Krug may have been in fact a Portuguese volunteer pilot Augusto Krug:

More info about him (in Portuguese) and a photo can be found here:

However there is still some puzzle to be solved - according to Portuguese info above Augusto Krug started to make operational flights only since August 1938 - thus the air victory claim of 27.12.1936 can not be attributed to him although it was certainly his Fiat CR 32 which was hit by enemy AA on 14.8.1938...
