Now that is a great variety of high grade cooking gear. Nice pics too. It's great to have options and to use a variety of gear.
I too like the bale for the crusader cup. Something I tried for a bit with the USGI canteen cup may work for others:
Take some heavy bailing/snare wire and make a wrap around the mouth of the cup just below the flared rim. Use needle nose pliers to twist the ends of the wire together to tighten it up. Next take two lengths of wire about 15cm long and feed the end of each wire under the loop around the mouth (imagine the kidney shape as having four "corners" the wire bales then go corner to corner in an X. Twist them back on themselves around the lip wire to secure them. I crossed them like an X in order to make the cup more stable when hung.
I realize this is not very clear. I'll post a pic when I get home tomorrow.
