Mehaniskais Konstruktors Skolens
Elektromehaniskais Konstruktors / Mekhanicheski? Konstruktor Shkol'nik (Мехнический Конструктор Школьник)

Elektromehaniskais Konstruktors / Mehaniskais Konstruktors Skolens was very similar to 1960s Meccano, except that the hole spacing was 12.5mm. The parts numbering was different to Meccano. It was made in Riga in Latvia in the 1980s. In Russia the system was known as Mekhanicheski? Konstruktor Shkol'nik (Мехнический Конструктор Школьник). As the names are just different sets/languages in the same system they really should be put under a common name in order to avoid confusion.
