Jim,
I can add a little to what you've already been told. Your O&R was mfd. before 1947. That year, O&R issued their radial-mount-only versions, retaining the small, elliptical exhaust stack. Later models employed very large, flared stacks and kept them through all later models.
It is possible the timer is OK but has been positioned 180 degrees off location. The timer arm position can be switched but, normally, the stationary point is nearly upright for running. The moving point actuator should extend through the slot in the crankshaft bushing to contact the milled-in-place cam on the c'shaft. If it does not, it is possible the c'shaft front plate will need to be rotated 60 degrees clockwise or ccw. When properly positioned, the timer slot will be opposite the timer spring. Internally, your timer appears to be complete and OK except for its position.
Good luck.
Jerry
