Jonathan Frost wooden works with alarm, 1841.  A 29.5-inch OG-style case with a cornice top, seen in several examples from this maker.  The mahogany veneer is good, a few chips but nothing serious.  The dial glass is period and may be original; the mirror is a modern replacement.  Frost appears to have made all his shelf clocks with mirrors. The dial is clean and bright and there is a period alarm disk in the center; the hands are period.  The movement is a 30-hour and is running and striking on a wire gong.  I did not test the alarm; it strikes a bell on top of the case.  There are two period weights and an alarm weight.  A good label that includes the date of manufacture.  As we know, wooden works with alarms are not common, but something Frost specialized in.  $100-$200.
