Where can I read about clock movements for a grandfather clock I would

Old '50s or '60s books on clock _repair_ for the amateur. They explain
the different mechanisms, and how quality/price can be varied by
construction techniques. With a little of that knowledge, a lot of the
commercial products become a lot clearer.
