VTG, chippy General Electric interval timer.
Face shows scratches and wear. Numbers are yellowed. Paint chipped. Great decorative piece!
From 1950s.
These were originally created to time x-ray machines and in darkrooms. It has a windup key to power the clock and bell alarm.
The chrome arm activates to turn a switch on or off when the alarm goes off. I've tested a couple of times, all in working order.
