Hey all   I am making up some kits for cattle wagons which are for the period circa 1926. Wagons which will be modeled are LNWR medium and large mainly with some MR wagons intermixed and also some early LMS ones.   My question is when was limewash/whitewash stopped in use on the wagons as a disinfecant? Information on this seems scarce/varied, some information says WW1, some as late as 1944 a notice was published, so does anyone have anything definitive please?   Cheers   David
