M: mini-sportgame variant exists !
C: Variant with coverless inner plastic box exists !

The early editions are published with coverless inner plastic box - some of them in "mini-sportgame" size.
All later editions have the standard size and the standard inner cardboard box !
The coverless variant of Speed Circuit is referenced in the 3M-Catalog - but not really verified.
