555A, 660A, 855X, 735A, 680A.
Its was called Direct Drive Tuning in an a article by, now sadly gone, Jeffrey Dixon-Nuttall. It apparently has concentric cylinders, like a Beehive trimmer, and the outer cylinder moves in and out from linkage from the push buttons.
If you fancy a complete radio then the 660A is good one to get as it has a tuned RF stage, some of the others don't.
Below is a montage put together by me from the article.
