Plans of Mitsubishi Ki-21 'Sally 1'
Here we see front, above and side views of the Mitsubishi Ki-21-I 'Sally 1', which featured an upper gun under a glass canopy and engine nacelles that weren't quite large enough to cover the entire wheel. The Ki-21-II 'Sally 2' and -IIa 'Sally 2' had larger nacelles, and the -IIb 'Sally 3' had a upper turret.
