Unknown maker, "Mystery" program clock, 8 days, time only spring wound oak wall clock, weekly program unit, with electrical contacts, below the movement, c1930 we do not find this unique heavy clock in any catalogues, but it appears to provide signaling and/or recording functions. The dial has an outer ring of small painted numbers, the hands have positions for contacts, the lower unit shows the days of the week. The open-spring movement ticks, with its simulated mercury pendulum, but was not tested long term. The front glass, with its decal, is wavy. The case is a Victorian design so the clock or case may be earlier. 42" x 19 1/2" x 7 1/2"
