This purpose is served by ζ-B.: A .small triangular pointer, .which: co is guided so that when the scale drum is / Draheh it moves parallel to its axis and “marks the individual turns of the λ scale band” . This pointer movement is enforced by a guide rail parallel to the drum axis in which the pointer foot slides. The "2-head" is driven off in that: a head part provided with a guide nose is inserted into a hat:
