To me this looks like a Kibo 1100 3-wheeler street sweeper. Kibo Kommunalmaschinen GmbH was active between 1964-1983 in Hohenbrunn bei München, buulding such vehicle with VW, Mercedes-Benz and Fiat engines.
FAUN bought the company in 1980. In 1983 Kibo became to IKF Industrie und Kommunalfahrzeuge GmbH - for a while both names were used (see attachment). In 1992 Max Pietsch GmbH bought IKF.
