Welcome James,
I'm afraid that's got more terminals than mine, It could be 3-phase,. or it could be to allow reversing.
Your insulation looks OK, but have a good look as older ones can have rubber insulated wires that perish and start fires.

For anyone who finds a simpler arrangement of connections (just 3) my single phase one is (don't follow these connections James!):
Live – 4
Neutral – 3
Earth – marked terminal on outside of case.
Capacitor 2 & 3
The red and green wires on mine go to the capacitor switch.
