Could you please help me identify this item? http://www.ebay.de/itm/Zeltbahn-Zeltplane-1-oder-2-WK-/141002814975?
I think it might be Czechoslovak (it shares some characteristics with post-war Czechoslovak "Swamp" quartershelters), but I'm not sure. The stamp is very hard to read (BTW it looks like being turned 180 degrees on the photos)
Thank you for your help!
