Dear Yvonne Kirk,
I have a few links that may assist you in providing some information on this subject,if nothing else they may know who to contact for futher information on this subject!
Can you get a book called "The Sawdust Fusiliers" (The Canadian Forestry Corps in the Scottish Highlands in the Second World War.)by William C. Wonders ISBN 1-895288-14-2
It may provide his unit number or give at least further information for you on this quest! 2 of my great uncles were with the CFC and were based in Northern-Scotland during the war.
Best luck to ye!
