New replacement for older movements marked 451-050 with an 85cm pendulum length and a bridge that sits flush with the top of the movement plate rather than on an elevated truss. These were commonly used in Piper, Wards, and Ridgeway grandmother clocks in the 1970s, among others. If you install the modern style elevated bridge in these clocks, the pendulum will not clear the chime block.
