small German cuckoo clock movement.

The stamping on the plate appears to read:

"Die 5 Minuten Ruf 32108-8"

That translates roughly to "5-minute call", meaning it is a cuckoo movement that can be configured to call every 30 minutes and strike the hours.

From the construction:

Weight-driven movement (one chain missing in the photos).

Regula-type Black Forest cuckoo movement.

Pendulum escapement with wire crutch still present.

Time and strike train.

Mid-20th century, approximately 1950s–1970s.

Designed for a standard Black Forest cuckoo clock case.

Condition:

Appears complete mechanically.
