I picked up another Ansonia, an iron case mantel, that was ready for the trash. Most of the paint was already off and needed to be sandblasted. I could not find the model in Ansonia Clocks by Tran Duy Ly, but the case looks just like the Lisbon (1014) but with lion heads on each side, and the dial does not have an exposed escapement. I replaced the pendulum, with a spring that is .001 thicker. I lengthen the pendulum and set the bob all the way down to the point it is just above the case floor. I still get about 151 bpm. I assume it should be 120 bpm. Is this correct? I switched to the old pendulum and it still runs fast, so not sure if this is the original pendulum and bob or not. The pendulum length stamped on the movement is 5 1/2. Thoughts on where to go from here?
