Chizhevskiy BOK-3 light utility and liaison aircraft

[Stargazer]

I have an article on this rare bird in the very first issue of Mir Aviatsiya from 1992, but no OCR software, so if anyone can tell us more about it... Thanks in advance!

Nearly seven years late but here's the data on the BOK-3. The BOK-3 was built in 1933 as a four-seat liaison aircraft with side by side seating (it was also known as Tsebrikov BOK-3 utility/liaison aircraft (see https://www.secretprojects.co.uk/threads/tsagi-zavod-39-tskb-designations.7286/)). It featured a semi-monocoque fuselage, with ply covered wings and fabric covered control surfaces. The sole example first flew in 1933. A number of variants were planned including a crop sprayer/seeder and a military trainer. The latter was to be fitted with a fixed forward-firing PV-1 machine gun and a manually operated turret fitted with a single DA machine-gun with provision for a single FAB-100 100 kg bomb or a reconnaissance camera.
