The case background color is tan, with deep red lines and swirls, and some orange swirls too. The dial is embossed brass. The date code on the bottom of the case is 5981 C (March 1895).
The clock strikes the hour and half-hour on a heavy coil gong (often called Cathedral gong). The movement is the 8-day "hip" movement (called that because of its shape). It has an American type "strip" recoil escapement in the back.
The case is 17 inches wide and 11 1/2 inches tall.
Repair job 6437. I made new rivets for the clicks, secured the regulator pinion to its arbor, polished the pivots, and installed 14 bushings. The mainsprings are original, and are as follows:
Time Mainspring: 11/16 inch wide by 0.0195 inch thick
Strike Mainspring: 11/16 inch wide by 0.0187 inch thick
These mainsprings seem thick, but had not caused much wear to the mainwheel teeth. If the springs needed replacing, thinner new ones should be used.
Repair job 6485. I polished the pivots, installed a new suspension spring (unit 11A with 0.0036 inch thick Horolovar suspension spring). I installed a new 18 x 38 mainspring.
I put "banjo" in quotes, as the original clock of this style was invented by Simon Willard and was called a "Patent Timepiece" because it was a new design patented by Willard, and it was time-only (no striking or chiming). Much later, this style became commonly called "banjo."
The photos don't show the finial on the top of the case.
The movement has the date code 4905 (May 1949). The motor is type M4 by General Time Corporation, which was introduced in 1948. The entire clock is made in USA, Seth Thomas started using German movements in 1956.
Repair job 6457. I polished the pivots and installed 11 bushings. The motor bearings had little wear. I lubricated the motor bearings with Molykote 44 Light by Dow Corning.
Repair job 6384. I polished the pivots, installed 16 bushings, and replaced the mainspring.
The case is 20 13/16 inches wide and 10 inches tall. The dial's minute track is 5 1/2 inches diameter, and the minute hand is 2 13/16 inches from center to tip.
The motor runs the hands, and winds the strike and chime mainsprings. Slip-clutch (brace) ends on the 2 mainsprings prevent over-winding. The movement is nicely nickel plated.
Repair job 6441. A previous repairer made file marks on the front plate when installing bushings. I polished the pivots and installed 21 bushings. I adjusted the chime mainspring to slip after 7 1/2 turns of winding, and the strike mainspring to slip at 7 turns. I installed new cloth-covered electric cord and a new plug at the end that plugs into the clock.
