My wife's stepfather recently died.  He had saved many things from the early 1900's to the present.  Among his belongings is the clock that is pictured below, which was given to me after his death. I've searched the Internet trying to identify it. He had an interest in railroading and other things mechanical so I searched for Locomotive clocks, Automotive clocks, Boiler Room clocks, Ship clocks, Aircraft
clocks, and clocks in general but so far, no luck.

At the bottom of the face it is identified like this: MADE BY THE NEW HAVEN CLOCK CO., NEW HAVEN, CONN., U.S.A. and the number 624.

It is all brass and quite heavy for it's size which is approximately 3 inches in diameter and 2 1/4 inches deep. The body was painted black. It has a thick glass and a threaded bezel. The speed adjustment is located at the edge of the face between the numbers 1 and 2. The face is also a brass color. The clock is made for mounting at an angle which tilts the face to the desired angle.

I don't understand this: I can't find any provision for winding it on the front or back. I first thought it was electric but there is no place to connect a wire. There doesn't seem to be parts missing. Could it be self-winding from vibration? I don't want to try taking it apart to see how it's made for fear of doing damage.

LATER: NOW I UNDERSTAND! When the clock is secured to a rigid surface, you simply turn the entire clock body in one direction to wind it and in the opposite direction to orient the face to the desired position.

My photos aren't very good so I included several of the face. Thank you for any information.  My Email address is:
