Splendid portrait of a Swiss “Emil” pilot. Our hero wears a mix of local and German flight gear. German are his LKp W 100 flight helmet with that nicely strapped 10-69 oxygen mask helmet and what seems to be “Auer” type goggles, or something similar. Of note the lack of canopy rearward armour and, barely seen, one peculiarity of the Swiss “Emils”: they’re equipped with a KG 11 spade grip instead of the usual pistol grip of that model.
All in all a very neatly dressed guy.
