Hi Thomas, and welcome,
Comments below, but my guess is as it's been working previously, the oil on the pivots has turned to grease and some or all have seized up. You will really have to dismantle the movement and wash everything out. Not as bad as it looks if you take plenty of pictures!

I have a Smiths Sectric table clock (with a larger T) which had been working fine and then stopped randomly.
I could hear it buzzing so thought I'd take a look inside.
Ive put a little light oil with the tip of a screwdriver on the various cogs Wheels shouldn't be lubricated, only pivots. inside, and have checked that there is power getting to the coil.
Although im an engineer of sorts this is not my area of expertise by any means and so please excuse my incorrect terminology.
The windings are encased in a metal box which appears to still be magnetised when the power is on. The stator? Rotor presumably has to sit just so in the middle of the magnetic field without touching the sides. Is this correct? Yes. In which case the rear securing plate doesnt seem to be particularly worn but I just wondered if I am missing something or whether the entire middle of the coil is supposed to be lubricated. No.
The other end of the stator seems to fit into a hole ok and match up with the worm gear. There is also a little sprung metal flap which seems to act as a non return spring so the stator will only go in one direction. That's right.
One point is that it had a two pin plug. Does that mean it should work with polarity switched? I've rewired it to a three pin plug and it had been working in this configuration prior to it stopping. As it's AC there's no polarity as such but it's not a bad idea to add an earth as you've done.
Many thanks in advance
