Yes, this "Junior" is a non-MVVS....it was made by a Czech manufacturer called "Start"...it is mentioned in one of Jiri Kalina's books (unfortunately I don't understand much of the text though...)

" Junior 2 were one of most used engines in 60s. This engine was used in all categories. Junior 2 was produced in 1958 in the company "START" in Prague.
