It sounds like it was a defective drive. These are common Jackson Brothers'
drives with two mounting forks. Two tapped/threaded holes on the outer
drive are used to mount the dial legends. Changing them is an easy job once
you find the drives; I've done it twice on the 86 models.

I wish mine had been that easy. In mine it was the friction of the vernier

with
solvent, but no luck.
