30 hour clock made between 1831 and 1837 by Austin Chittenden, Lexington, Massachusetts.  Nice clock, runs and strikes.  Top glass is original, middle glass looks original and I'm pretty sure lower glass is a replacement.  The clock is 31" tall,  17 1/4" wide and 4 1/2 " deep.   The weights are on a double pulley as shown and travel down the columns at the front of the clock.

I offer no guarantee for clocks that are shipped.  I will meet halfway if it's a reasonable distance.
