I have seen 1 walkie talkie total. I found 2 blood test kits, not in the same day, and my buddy found 1. As for the mosin compensator... never seen it, nor heard of it. As for the rest, it seems like sometimes certain items spawn more than others. I had 1 life where I found 2 clips for the FNX45 right off the bat, then found the pistol a few minutes later. I've had times where I saw 6 compasses and no food, and other times 0 compasses. I've seen the respirators a bunch of times and not others. One life my buddy and I found 3 maps, another time 2, and a couple of times 0. I've had 2 lives where I had a mosin, one of those times I had no ammo for it and no food. I've had times where ammo was abundant, and others not. It may also be dependent on the server. I don't know if a server ends up with random loot every time it restarts or if it stays the same loot table as the first time it started running DayZ. I have bounced from a couple of servers when I died because there was no loot near where I started a few times. Sort of hard to survive with no food or water, and when people who are fully geared are camping the starting areas. I've traveled a few towns north and found no supplies because they were all gone. Anyways, I think I've seen most of the items so far at least once, except for the magnum rounds.
