Itrem ID: 2421 - Welch, Spring & Co. No. 4 Regulator - 30 Day. This is the finest example that I have seen. The clock is mint original in every way. The walnut case is flawless. The finials are all original and flawless. While I have not seen another Welch regulator with Arabic numerals, this clock shows no signs that the dial has been changed in any way. The 30 day movement iwith nickel plated plates is in fine condition. An amazing clock.
