thanks for showing us these hirschfangers, I hate to be the one to tell you but I have my doubts on all 3 of them,

The first one you show is the long deluxe Horster DJ, there are a few original pieces out there, without a hands on there's certain features I do not like.
The second one is supposed to be a short deluxe WKC forestry piece, it lacks the proper detail in all the fittings, the blade etch is poorly executed and the grip acorns are not right for a WKC.
The last one is the easiest, it is an Atwood fake from the 1950's, an etched mark on a brass based Holler is all wrong.
