This is what gives the challenge if collecting. If there were no fakes it would be a bit boring after time and many would start collecting. With fakes, it gives the challenge but you just have to be careful. As far as things made up after the war, I don't consider them all fakes if they were within a certain amount of time. They are still original parts and are a unique part of history. As far as comparing to originals, it would be impossible without older collectors who collected before the modern fakes.... So older collectors are a a good source (most of the time) as if they had seen something at that time and can confirm it existed or they had seen one can help come par to an original
