This 8 day brass movement Forestville Clock Co triple decker clock was acquired with a broken center reverse glass panel.  I decided to repair the broken glass as a temporary measure while I decided what to do permanently .  All but a few slivers of glass were inside the clock, using a conservation quality glass epoxy I pieced the plate together.  I used the epoxy to fill in the missing parts. The proper adhesive is important as something less will yellow with age and not provide a permanent bond. The appearance of the panel is such that i have left it in place and think this maybe the "permanent" repair.
