Comments: A rarely built and sold cross between the SL 220/221 and SL 3310, therefore not to be found in German brochures. The highest quality belt-driven SL Technics brought to market. Most of the technology was still used in the SL B 300 from 1984. Identical in construction with the SL 230 (silver).
