Fake or Fantasy Milk Bottles

Lately I've noticed a lot of Fake Milk Bottles on Ebay,  This seems to be limited to WW2 and other worldwide events, To Make Sure you're getting the real deal, check for Bottles that the screening just looks to good, Check the dates on the bottom of the bottle, it shouldn't be 1949, the top should be correct for the bottle, not a modern top, Probably the best advice is purchase a milk bottle book from John Tutton, he has a complete line of fakes, Also Know your seller. Hope this helps.
