R129 Supercharger???
I have seen a MUCH LESS refined kit offered by Koenig where they fit a cintrifugal type to the side. This is a really poor design, but the only one available for the 119 engine.
Check if you have 1 spark plug pr. cyl or 2, if you have 2 pr. cyl, you can be the lucky owner of a KLEEMANN SC.
