I've fairly recently came into the possession of my grandfather's WW2 Soldier's Service and pay book & a boarding pass for a ship (with no date provided) and was wondering if I could get some help figuring out as to what unit(s) he had belonged to. I've contacted Archives Canada at the beginning of the year and and I am currently awaiting a response from them (after the initial acknowledgement of receiving my request). I have came to Army.ca to see if anyone could be able to understand and relay to me what unit he may have been with. For some background information on him: he enlisted in Nova Scotia in May of '41 with a Scottish ethnicity & by trade he was a storeman. His boarding pass is too large to upload on the forums but on it it has his Number (F78833), Rank (Pte), and his unit information ( CD 541/MD 6 (3 [The rest is illegible to me])Any help would be much appreciated, thank you!
