With the closing of the 1970s the venerable Lark design took a small, but significant steps forward. The cable clamp was mounted on the outer parallelogram plate - changing the geometry of the gear, as previously the cable clamp was attached to the front knuckle. The spring-loaded cable saver was also moved from the cable clamp bolt and built into the outer cable stop. All this clearly deserved a change of name - to Lark II.

This example has a Japanese-style backwards hanger plate.
