    Lovely 400-day Miniature

    Just bought this lovely little pin-pallet miniature, whose I think is Plate 1406C (KS) in the Terwilliger 'bible'. The back plate measures 4.35 x 5.2mm and has the strange KS symbol, BUT no other name as in the Plate. Anyone know anything about this clock? Is it a Kern & Söhne clock...

    400-day clock - ball pendulum problem
