An oddity from Augustusburg

A prototype engine seen in the motorcycle museum in Augustusburg. Acording to the plaque this was the IFA L60 from 1948 with "Kolbenladepumpe" and "Kardanwellenantrieb" which if my German is right is a piston supercharger and a shaft drive transmission. However a power output of 2.2KW ( approx 2BHP) was probably dissapointing!
