ramtank2;
Might I suggest that you purchase these three books:
Tools of the Trade, Equipping The Canadian Army - $29.95
The Ram Development and Variants, Volume 1 - $ 9.95
The Ram Development and Variants, Volume 2 - $ 9.95
which are available from Service Publications, which can be found
here
These three publications would answer all of your questions on the use of the RAM by The Canadian Army during the period of the Second World War.
Cheers
