Need some help with these Army daggers

[pocket]

Hi guys, what do you think of these army daggers.

 

Are they legit? Anyone dares to name a approx. value for each one? Also, the seller is naming specific types, from the research I did it seems right but I'd like to have thoughts on that as well.

 

Seller info:

From left to right:

Rare WKC Type 3 in excellent ++ condition

WKC type 4 mint

Hörster 2 mint

 

 

 

 

I got some more photo's of the Hörster:

 

And some more of the WKC type 3:

They all look good to me.

Thanks @Preppy Picker, Do you have any idea what a fair price would be for each one? 

I'm just starting to learn about army daggers I don't want to burn myself first buy:) trying to figure out how desirable/rare each one is.

pocket, I would start by seeing what major dealers have in stock in the US. Tom Whittmann at www.wwiidaggers.com, Thomas Johnson at johnsonreferencebooks.com, or Bill Shea at www.therupturedduck.com. Prices will be in US dollars and do not forget that these are dealer prices so, expect to get less but they all look like good sellable examples.
