This is a staunton set in plastic.
This set is not weighted and it has a German knight.
These knights are a simplistic representation of the piece and became usual in German and European sets from 20th century.
It is a typical club set that is available in Europe mainly.
Also the design of the bishops has some resemblance with the german sets of 30-50s of 20th century, where the bishop appears sometimes with a "missile" form.
This set has been seen for example in the analysis room of the Tata Steel tournaments.
