More about the 22nd Armoured Brigade on 22 December 1941

I know a bit more about the 22nd Armoured Brigade, as it was on 21 December 1941:

22nd Armoured Brigade

composed of
3rd County of London Yeomanry
4th Country of London Yeomanry
both equipped with a total of 80 Crusader tanks
  (I would suppose about 40 Crusaders each)
2nd Royal Gloucester Hussars
equipped with 30 Stuarts, which might be
about 9 Stuarts per squadron with 3 for the HQ

This is based on information in Vol.III of the Official History
