Probably not, at least for WWII issue. The first patents on vapor-phase corrosion inhibitors (VPIs) for ferrous metals were issued just after WWII and into the early 1950s, and typically reference salts of volatile organic cycloamines. I've understood the first commercial-scale VPI use was during the Korean War era. I don't know exactly how, but I would guess that the organic amine salts were incorporated or impregnated into the wrapping paper. Any corrosion preventive papers used prior to the early 1950s must have used some other principle. What happens is that the salts are slightly volatile, and the organic amine vapors released are continually deposited on the ferrous metal surfaces, coating and sealing it against contact with water vapor - much like waxing the metal surface.
