That upper works was used on the Class M, the early Spring Motor, the Class T (Treadle), and the Class W (Water Motor). The serial number dates it to around 1899, so it was used with a Spring Motor or Class M. The carriage is 1910 or later, and is inappropriate for a 2-minute machine since it accommodates a Model O (2 & 4-minute) or Diamond B (4-minute celluloid only).
