I did a quick check....looking at several differant sections (Helmets, bayonets, field gear, "German", WW2) and while what I saw appeared "real" enough.....some was mis-identified, most is WAY OVER-PRICED, and very little would be considered true collectibles.....most is "Army Surplus" (even the WW2 stuff...of which there's very little) and NOT really collector grade material. (a couple exceptions....but still over priced!)
Depending on what you're looking for, maybe a good source.....but I didn't see anything I'd want to buy for them. Most "Army Surplus" dealers don't know crap about original vintage artifacts or their true value....unless you're looking for modern stuff....and you can buy 99% of what I saw at about HALF what this guy's asking....
My opinion only....but not where I'd buy Militaria!
