As a collector of East-Bloc gear I can tell you from personal experiences and experiences of several friends that soviet-power frequently ships incorrect, commercial or low-quality copy items instead of what is pictured. Also stay away from frontofrussia I recommend soviet-propganda.com
Yup, lots and lots of commercial stuff there. However, they do have quite a bit of genuine issue stuff. I can't speak to the problems others have had, but I had to order a hat for a friend and it arrived quickly and was exactly the item ordered (including size).
I was gonna order from Sovietmilitarystuff.com but their website kept getting weird code errors. But it had the exact same stuff from Soviet-Power.com. I did manage to find a seller on eBay selling similar stuff. I ordered a set of Flora and Bhutan along with a Soviet Afghanka hat (the one with the flaps).
The Flora looks practically new, is well made and has all the right government stamps. The hat is authentic as well. The Bhutan is ok, looks to be some Chinese copy though and there's no stamps and only a tag with a number on it.
So it's really hit or miss. My best advice to you is if your going to order from a website like this make sure its reliable and that they use Paypal and buy the more expensive stuff. I know that sounds weird but its more likely to be authentic.
