Comments: A rarely built and sold cross between the SL 220/221 and SL 3310. Therefore not to be found in German brochures either. The highest-quality SL belt that Tech nics has brought to the market and whose technology was mostly still used in the SL B 300 from 1984. Identical to the SL 230 (silver).
