The mechanism you are referring to is called "auto break" and your 101 does not have it. The two things stopping your 101 most of the time. The break mechanism on the bottom right, or a misadjusted speed control (bottom left).
The movement of the tonearm is in no way connected with the motor.

I see. So the turntable moves when the 101 is wound up and the only way it stops is if it needs re-winding or the break is on or there is a problem with the speed control. The arm and sound box have nothing to do with it.

Thank you so much I have learnt a lot there.

Oh, I have just noticed something.

I removed the turntable and looked at the speed lever / controller.

Towards the end there seems to be a part which is raised and 'sits' on top of another part. It looks like it should be lowered so it 'catches' the other part. Should I lower this I wonder ?

It works !

I moved the lever back in position and the turntable is spinning happily away - another happy ending !

Thank you all so very much for helping me.

Even though the motor now runs, it is a good idea with any newly acquired machine to remove the motor board and lubricate the external moving parts of the motor i.e. gears, bearings and the leather pad which bears on the brass disc of the governor. This simple maintenance will help to promote smooth and steady running.

In case you were wondering, later versions of the HMV 101 did have an automatic turntable brake, but of a different design than that of the 102.

Thank you very much for your advice. Very interesting to see the automatic turntable brake on later models.

Oh, one final question I think.

What is this behind the 'arm'. The HMV 102 has a needle box holder but this seems too small ?

This is a tungsten needle tin holder.

As Teak says, it's for a tin of HMV Tungstyle semi-permanent needles (called Tungstone in the US) - the tin is longer, slimmer and narrower than the usual tin shape.
