Ushanka? Need help!

[Schweitzer]

Hi,

I want to buy a genuine unused blue-grey soviet era ushanka from the eighties, like this one (picture from wikipedia):

I have been searching the internet for a few days but the offers are a little bit confusing. I have the impression that a lot of sellers just put some kind of badge on a ushanka to make it look as if it's from the soviet era.
I don't know what to look for exactly, any help is greatly appeciated!

A few questions I have:
1.) Is the supply for unused, genuine blue-grey soviet era ushankas (ushanki?) from the eighties rather big or small?
2.) What would be a fair price for such a piece (size 59 to 62)?
3.) What sizes where issued [ (...58...59...60...61...62) or just (...58...60...62...) ] ?
3.) What do I have to look for to distinguish the real ones from fakes?

Here's an example I found from a seller from the Ukraine, I think he sells via ebay too:

Sizes available from this dealer are S(54), M(56), L(58) and XL(60). Does this one look real? Price (including shipping) would be 25$ (I live in Germany).
