Wm. Gilbert “Octagon Drop Calendar”, 1861-1866.  A second version of the Maranville calendar; a similar example is shown on page 72 of Ly’s book Gilbert Clocks.  This one is 22.5 inches long with a rosewood veneer around the bezel, with some wear, and an interesting pattern on the lower door.  That door has an original Gilbert porthole glass; the dial glass is modern and the metal dial nicely repainted.  All three hands are also new.  As with #22, you have to advance the month and weekday calendar dials by using the winding key on the studs at the top and bottom of the calendar.  The 8-day time-and-strike movement is signed and running, striking on a wire gong on the hour, the calendar hand is advancing.  There is a good label inside.  This model is less common than #22, but typically sells for $400 or so; Cottone’s sold one last year for $450.  $350-$500.
