I like Sessions Long-Drop School House clock because the case is a little different from the Ansonia or Seth Thomas versions in that the lower section is much wider.
Overall, this clock came to me in great condition with a heavy cast iron pendulum. It is an 8-day, time only clock. Mass produced in the late 1800s, the movements are typical of the cheaper clocks. Ansonia or Seth Thomas both have much better quality movements. This particular clock works well considering all I did was refit the verge and adjust the retaining arbor that secures it to the escape wheel.
Time-only movements are the easiest movements to work on when one is starting out.
