The cast iron pier that supports the telescope mount. | |||
The clock is mounted at the top of the pier, two doors with windows are on either side for access to the clock. | |||
A solid door near the base of the pier provides access for adding weights to the clock. | |||

A brass knob 3/4 of the way up the pier seems to function as an on/off switch for the illuminator. It also has a rod attached to the back that may have functioned as an on/off switch for the clock drive as well. |
