2 gong chiming clock movement with key. Purchased by my father in the 70s, new from a company believed to be called Grenvilles who specialised in supplying quality clock movements. He mounted it in a hand made mantel clock.
It would be an easy repair for someone familiar with the work, as it simply has one gear wheel which is out of line, as though the end of it's akle is broken. Otherwise in excellent condition.
