    Hi everyone,
    I have a couple of questions about a 1924 S.T. #4 movement that our state Chapter is restoring as a public project.
    1. Can anyone give us some ideas on correct/authentic paint colors? These plates and the top bridge still have some flaky brittle flecks of red, the weight plates and the pendulum bob are a dull green, and the rest of the weight and the support base are black. There are so many "reds" available! Is there a standard or original color that we should look for? Are the brass wheel spokes usually painted also, or lacquered?
    The latest coat of paint on the cast iron case was black, but there is evidence of a green layer somewhere beneath. We would appreciate any recommendations!

    2. The only way we can see to set the hands on the four dials would be to loosen a lock screw or two in the hand drive take-off system, either at the universal joint above the top bridge, or on the bevel gear on the second arbor which drives the vertical shaft. If one of those options is taken, then the setting dial on the front plate won't match the 'public' hands. There appears to be no disconnect at the escapement for free-wheeling that I have seen in bigger tower clocks. This photo shows the minute arbor where the setting dial is placed in front and the hand shaft take-off in the rear. Does this large nut holding the wheel in place have something to do with changing the hands?

    Thank you for any advice!

    Here is a photo of the movement just as we found it in the case - difficult to see much detail of parts due to the horrific electrification job that was done long ago. But you can get an idea of the remaining color on the plates. Fortunately the pendulum and removed escapement parts had been stored in the case.

    The second photo is a page from a recent Bulletin showing an example of the same model clock that sold at auction - the only difference would be that 'ours' was originally made with an automatic electric rewind mechanism for the weight, so we have no winding arbor and a straight pendulum rod.

    As for the color question, all the examples I see are a matte black finish. Here's another:

    Well - one question is solved - the #4 street clock movement DOES have a method for allowing the train to "free-wheel" to set the hands. We hadn't realized what the big lock nut on top of the verge is for, but this allows the pallets to slide away from the escape wheel teeth, which, being controlled with the other hand, can spin until the hands are correct. Thank you to the knowledge and resources of the Tower and Street Clock Chapter 134 ! (Escape wheel is not in place in the picture..)

    Most of the number #4 Seth Thomas movements I've seen have green plates with black accents on the edges.

    Ron, I love your display. What material is the dial made of?

    the dial was the original dial inside a jewelry store - it is a back lit milk glass with a beveled over glass and a mahogany bezel IMG_7584.JPG The weight dropped in-between a studded wall with the movement on the first floor and the dial in the inside arch of a cathedral ceiling

    Milk glass is actually called "Vitrolite" with the small groves in the back to defuse light. The product is not longer manufactured. The square base pedestal is the last style manufactured by Seth Thomas.
