C.1890, Seth Thomas, “Regulator No. 19” wall clock
in oak, in very good condition, with restored dial. This clock hung in a Manhattan building and was boarded up out of sight in a small room between the wars. A few years ago, when the building was being remodeled, the wall was knocked down and there was this clock. Somehow word got to Mr. Rappaport and he immediately negotiated the purchase and carried the clock out to his home. The dial had flaked and has been professionally refinished. The case was cleaned with beauty rub and still retains original finish, with minor blemishes. It is an attractive light oak color. Hinges, latches, pendulum, weight and hands are original. We have the mercury in a lexan container, and are advised that it is not possible to ship the mercury, so you will need to make arrangements to pick the jar up in person (or have one of our private carriers bring it for you). This model is discussed in Ly’s 1996 Seth Thomas book, pages 128-135. Height 75″

The MOST amazing part of this clock is the original painted dial which has survived with only minor paint loss. It also retains lock in door and with key (donit lose this).

Seth Thomas Clock Co., Thomaston, Conn., “REGULATOR No. 19”, in walnut with burled appliques, wall regulator with 2- jar compensating pendulum, weight driven and with center seconds hand, c1885
another fine clock from Milanville, PA. photo shows the clock hanging in the Wasserman home. For a truer image of the rich color of this clock, see the close up of the top and bottom. To minimize flash back, we took the main image from the left and lost a bit of detail. Like most of the clocks, Bob W. acquired this one with a lightly crazed finish and he rubbed and waxed it with a minimum of loss to the finish. Stated briefly, the clock is in outstanding original condition and sure to please the most discriminating collector. Nickel finish on dial bezel, weight and pulley are intact. Original dial with only minor losses near 12 and 6 from setting the hands. Additional details on the #19 may be found in Tran Duy Ly’s book on Seth Thomas, 3rd Edition, pages 301–303. Movement is running briskly and is generally clean, however some of the oil has congealed and it would benefit from disassembly, wipe pivots, reassemble and oil. Movement is numbered 293. This earlier case has tulip pattern carving on the door. Heavy iron movement bracket has been painted black; has proper wide saddle for mercury pendulum. Original door glass is wavy with imperfections. Ht 75″
