I am trying to narrow down canadian units camped near the Norfolk/Suffolk county border in the fall of 1943. More specifically, units that left the area in the first days of December 1943.

I have read the report No. 104, and have narrowed down two possibilities:
4 Cdn Armed Bde at Lyndford Hall, Mundford and 4 Cdn Armed Div, at Cockley Cley, Swaffham

Can someone point me to somewhere I can find out which specific groups/regiments made up these two at that specific time? I'm having a hard time following all of the changes and amalgamations.

Thanks,
Val
