[Sergio Luis dos Santos]

Many thanks for confirming the unit. It´s a great help to produce a color profile for my Fw 58 book. The seller confirmed that some of the photos had Derna on back so its safe presume all them were operating at Stab Flieger Führer Afrika

I do not have any other info on Stkz or W.Nr. (except for two photos I have from 1st. and - not sure - 2nd or 3rd prototype) I have downloaded and saved around 5 thousand images from ebay and will search the ones with the Fh 104.
