So I'm a bit of a sucker for combat boots and military stuff. Of course, these boots are leather. I found a bunch of surplus from the vietnam war that are not being manufactured anymore, so they're practically antiques. I'm hesitating a little bit to buy these, because I don't really know what to think of it. What would you guys think of buying leather combat boots or a survival knife with a leather sheath if they're from 1967? I would appreciate some feedback!
