Seth Thomas “Regulator No. 1 Extra”,ca. 1880.  The case is 41 inches long, just short of the 44 inches reported for this model.  The original rosewood veneer is in perfect condition and well-polished.  Both glasses are wavy but may not be original; the tablet has been retouched and rebacked, the dial has been repainted.  The hands are proper, but the minute hand has been lengthened.  The movement is a puzzle.  It is a signed trapezoidal plate, 8-day, time-only, weight-driven movement that I cannot find in Ly’s books on Seth Thomas clocks.  Notably, and in contrast to most ST Regulator No. 1 and No. 1 Extra movements, the pendulum is suspended behind the movement, such that the weight falls in front of it. This does not make sense when the lower glass is designed to show the pendulum bob swinging directly behind the glass.  This “reverse” arrangement was standard in the No. 2 and No. 3 regulators, neither of which had a tablet with a pendulum window.  A nearly identical movement can be seen on page 277 of Ly’s Seth Thomas Clocks & Movements, Vol. 1, used in a No. 2 regulator, and on page 279, used in a No. 3 Ball regulator.  The brass weight here has knurled endcaps, as did No. 3 weights.   There is no label in this clock or a date on the back, although it appears a label was on the inside bottom of the case long ago.  With all that said, the clock is running fine, but the dial must be positioned properly to avoid rubbing with the seconds bit.  You may notice a blemish or two and light wear on the dial.  Regulator No. 1 Extras are uncommon; Schmitt Horan sold one last month for $3000, just like in the good ol’ days.  $1000-$3000.
