Working on my pack, got everything I need except the Sonix, the "bee stinger/canteen/faucet cover" and "cistern/siphon". Apparently it's the wrong time of year to get faucet covers... I have heard, however that there are a few people who make reproductions of these items and was wondering if anyone could put me in touch with these individuals.
*EDIT* Got the canteen covered (Thanks to RoCKo and M4vrick)
