Model E149. Not a precision instrument. My father in law was stationed in Germany around 1965 and enjoyed woodworking. We inherited this clock from him. It's powered by rocks and a rope (not pictured, but they gotta be around here somewhere). Face is stamped West Germany. Wooden movement: Identified by Google search. Needs work. The wood has dried out over the past 50+ years and the frame has gone from a rectangle to a parallelogram, so the escapement doesn't engage. I pushed it back into alignment but have no faith that it will hold. At this point I'm keeping it as a family keepsake/curiosity, and posting it here so anyone who runs across one of these will know what it is. Currently hanging in my Dead Clock Gallery. I think there's 3 feet of cord and two rocks in the movement. I think it'll go 12 hours on a winding, but since it hasn't run while I've had it, I don't know. I suppose with a longer cord it would run longer. Put it at the top of a telephone pole and you could make it an 8-day clock. Anyway, that's what it is.
