I bought this Colonial clock as part of a collector's estate. It was running OK, but the strike wasn't stopping. I went through the movement, which was very uneventful. Upon reassembly, the clock is running and striking like a champ, but I've discovered that the clock runs not quite 6 days before the weights hit the bottom of the case. As far as I can tell nothing has been changed - I have no reason to believe the movement didn't originally belong with the case. I thought that perhaps the weights are a replacement and taller than designed, but I would need about another 15" of weight fall to get this thing to run for more than a week. Did Colonial make 5-day clocks? It seems very odd. The movement is stamped Colonial but the winding chains are longer than they needed to be, so I suppose it's possible it's a marriage. This is a clock that I need to find a new home for - an oddball wind-one-and-a-half-times per week characteristic isn't going to help its resale value. More photos in my blog link above.
