well it looks like Dave Lau's never ending search and mine ended up at about the same place,the Swiss Army canteen cup.i like his idea very much and as i still have the canteen i'll do some cutting and fitting and see how it works out.the ability to have a pot to cook in and a cup for hot drinks is great and with some good tape with a string under it i should be able to make a WP kit with a "zip" type opener for ease of use.i will have to remove the bale from the cup but that can be stored and replaced with ease.
great link-thanks!..it's 1AM here but i'll go down to the gear storage in the basement and dig out that canteen!!
