No Chris, the 'Emil' cowling was a different shape and size, with a 'square' supercharger intake and ducting. It's a standard 'Friedrich' cowling, and almost certainly yellow in colour, the dark colour (often mistaken for red) being the effect of the orthochromatic film used, or possibly a B&W print from a colour negative, made on ordinary B&W 'Bromide' paper. (also seen on the lower half of the rudder.)
It's very possible that it is the same aircraft as shown in the photo below it, before the winkel was painted, but after removal of the factory delivery code letters.
