Konstruktor(4) (including Konstruktor(4A))

Konstruktor(4) (including Konstruktor 4A) was a Stabil-like construction system. It appears to have been made by a number of different manufacturers over the years. However as the parts and models including drawings in the manuals appear to be all very similar (many identical) and all with a 12.5mm hole spacing, I am treating it as a single system. It was made in Russia/USSR from the 1930s to the 1980s.

Comments
Set similar to KONSTRUKTOR [4] but coloured parts, & thus it may be earlier. The Windmill model shown on Ebay is identical to one for KONSTRUKTOR [4] but crudely drawn.
