Hi all, The following image is from the section on Canadian-made Valentine tanks in Design Record, Canadian-Developed Military Vehicles, World War II. I'm interested in digging down into these original reports at LAC if I can find them. I believe the War Museum's research centre has the tank instruction books. And I think I have found the LAC archival reference for the Field Trial Reports. I'm guessing - from the article on the Skink in wikipedia - that D.M.S. is Department of Munition and Supply, and A.E.D.B. is Army Engineering Design Branch? What about HQS, D.A.D., and I.B.U.K.? I'm also trying to make sense of "Tanks and M/T Library Ref" -- was there a Tanks and Motor Transport Library at one point?
