Item 185

This is a complete mechanical assembly from an old School time clock system than automatically rings the bell for start and end of lessons, and beginning and end of the school day. I've converted several of these before, and I motorise the mechanism and add a Nixie Clock in the bottom left corner, some pictures shown to give you an idea.
For this one, I would construct a nice wooden frame and have it as a wall mounted piece

A large and pretty heavy item, measuring 43 x 43cm and 15cm deep.
