The pcv valves were probably on many engine marques including non military stuff, through into the 1960's (I could be dreaming of course), so shouldnt be hard to locate at a reasonable price. The Breather has been covered in another thread by Tony Smith. Basically the oil bath breather stopped the engine sucking in the dust, that wore them out quickly in the desert. Probably not going to happen to yours, even if you cant locate the right one.
