German Cuckoo Clock

We were given this from a family member & would like more information. (A research site for cuckoo clocks would be nice) Front top says Elgin, bottom says Germany. Wooden face, plastic hands & cuckoo bird. Turn over on back has white "Germany" stamped on upper right. Clock was bought at the Clock House in Norfolk, VA, Aug 72 #13965 (store no longer in existence) Inside- Huberherr, Triberg, Germany. Clock works unadjusted & no jewels. Any info is helpful & needs major repair.
