Ergo Wind up Chime Wall Clock

Beautful wind up wall clock - only manufacturing marks are stamp on Back saying West Germany.

Marks on the pendulum are finger prints only

Clock face has Ergo stamped into Design - clock face is 8 inch diameter

There is a hand written sticker with price and V number - think it is inventory numberV100730612

Clock movement is Jauch Nov 1979 - Stamped on clock movement Back

Part of back chime assembly has number Stamp H108S

Clock can be set to Silent, Westminster and Ava Maria - chimes

During Silent mode clock still has a tick tock sound. Keeps perfect time.

Would like to know the current value and any history on this beautiful time piece.
