Old military skins

Anyone every use these?  I can imagine they are pretty gnarly since they appear to have been designed around the timeframe of the Korean War.  But they're also $30, and I can deal with some gnarliness when the price is right.  I'm almost tempted to buy a pair just to see what they how they look, but figured I'd ask on here before wasting the money.
Thanks!
