See also Mercedes W115 and W123 240D. Even the ones with a manual transmission had a clock where the tach would go. The speedometer had a series of dots at particular speeds that indicate the shift points for each gear (e.g. 1 dot for 1-2 shift, 2 dots for 2-3, 3 dots 3-4). I'm not sure whether a tach was even an option. The higher spec models had them, though.
