Konstruktor(23) Construction Sets
Konstruktor(23) was a copy of 1960s Meccano. Its manuals and models were also almost identical. It was made in Russia - probably in the late 1960s. The hole spacing was 12.5mm instead of the 12.7mm of Meccano
Info from the Metal Constructional Systems Database
Hole pitch <12.7mm(some significant doubt)
Bolts: round (slotted)
Manual models are from 1960'S MECCANO, also parts but tho hole pitch given as 12mm. Very similar to YUNOST' but its hole pitch is 12.7.
Below there are manuals/leaflets and photos which can be downloaded by clicking on the appropriate image.
