The musty smell on military surplus seems to be de riguer. I personally think they have some aftermarket spray to make as new merchandise stink ;O). For the plastic canteen lots of hot soapy water and soaking in baking soda should do the trick. The metal cup has a small "stove" that was used to heat meals in the field with trioxane bars or tinder. That is the discoloration. Again, lots of hot soapy water will make it useable. Surplus sales are tricky. If it says as new or excellent buy it. Phrases" like used but good or still serviceable" mean repairs needed. "Military style or type" translates into Mainland Chinese junk junk junk. Try to avoid overloading on surplus, simply because of the image problem. walking around in full cammies and web gear during a disaster gives the impression your part of the rescue personel, a looter in disguise or a Rambo type. There are lots of resources in Doug's retail list. take your time and buy right once. We all have closets full of mistakes ( well not me anymore, sold it to a Rambo type this weekend.)
