Drawing by Tapani Tuomanen

Two photos of an high altitude R-Z prototype of 1937.

The plane seems painted silver overall, with a cherry red (?) decoration on the fuselage, apparently extended to its undersurface, the landing gear struts and the wheel fairings.

The only visible mark seems a thin red star outline with internal circle on the rudder.

Photos from Armada n.22, R-5 and R-Z, of M. Maslov and Aviakollectia 5/2009 R-Z of V.R. Kotelnikov
