Konstruktor(20) Construction Sets

(including Konstruktor Voennaya Tekhnika)

Konstruktor(20) is a Meccano-like construction system with similarities to the German Eitech "Construction" system. The sets and manuals all have the 'ЧЭАЗ' (CHEAZ) and/or Russian Style logo on them.

In the late 1990s the CHEAZ range initially consisted of the two sets previously made by the Brest Engineering Production Association in Belarus (see Konstruktor(27)). The system Konstruktor Voennaya Tekhnika, should be merged with Konstruktor(20) as it is just one of the sets made by 'ЧЭАЗ' (CHEAZ). You can see the current CHEAZ range on their website and is also shown below - https://www.cheaz.ru/products/gds/children/constructors.html. 'ЧЭАЗ' (CHEAZ) construction sets have been made in Cheboksary, Russia from the late 1990s to the present day.

You can see from the CHEAZ website that they also produce some sets in conjunction with 'Русский Стиль' (Russian Style) which is based in Moscow. These joint sets have both the CHEAZ and Russian Style logos on them.

Russian Style also market some additional sets which do not have the CHEAZ logo on them. However the parts in these appear to be identical to the CHEAZ sets and could well be actually made by the same manufacturer. The Russian Style website is https://www.russtyle.net/. Русский Стиль (Russian Style) makes/markets a wide variety of other toys in addition to the metal constructional system.

The actual manufacturer of the CHEAZ sets is almost certainly the same as for Samodelkin (Самоделкин) sets because some of the sets of both systems share the same design of packaging although the set contents are different. Both Samodelkin (Самоделкин) and CHEAZ (ЧЭАЗ) are in the same town - Cheboksary.
