"Just noticed what looks like a prop on the nose of the aircraft?"
A thought on the Trimotor at right, while agreeing that an ANT-9 is a likely candidate, didn't they all have two-bladed props? This one clearly has three-bladed, so how about a PZL.4 which had them as standard and also fits in the time-frame!
Hi. Thanks for that, when I zoomed the photograph it was not clear but fuzzy and I was not sure if it was a prop or an imperfection. Regarding the Trimotor in Bill Gunston's book "Tupolev Aircraft since 1922" there is a photograph of the prototype ANT-8 after being fitted with Wright Whirlwind J-6 engines and three bladed Hamilton propellers.He goes on to write "Conversion began in 1933 and by 1934 most re-engined aircraft also had Townsend ring cowls.".
