Default Help Identifying a Motor

Hi everyone. It's been a long time since I've posted, but I need help identifying a motor. I've been tasked with restoring this old moving artwork at my school. There are these strange motors that move a drumstick and hit it on a drum.

The motors have very limited travel, they only rotate about 45 degrees. There is a hairspring that provides restoring force for the motor.

I have attached a few pictures. There is a plate that mounts on the surface and is connected to the hairspring. I took the plate off and wasn't able to put it back correctly.

I really appreciate the help in identifying the motor. Thank you.

Those are rotary solenoids. If you Google the term, you'll find lots of information.

Plate now facing the wrong way?

As Frank says they are rotary solenoids.
