Seth Thomas "Regulator No. 4", C. 1917, when the movement was first introduced by the company for their No. 2 and No. 4 Regulators. They called it a Keystone shaped movement, with heavy polished plates, Graham dead beat escapement, maintaining power. It is fitted to an iron bracket. The number is 77B, and it is 8 day, weight, and time only. Mahogany case is 42" high, refinished some time ago. It is not a mint collector's clock, but is a very good looking, serviceable, running, wall weight clock, which is what most people are acquiring these days. There are 2 brass door locks, the original 12 inch zinc painted dial, with a second's dial, and all original hands. The brass bob, weight, beat scale, dial ring, are all clean.
