Mike..that was me.--i'm doing the Swiss Army canteen cut off as a container.i have the pot and cup part done and took a few photos but i'm still working on the contents of what will be the food side of my PFD ditch/survival vest.when i'm done i'll do a new post of the results.mine will be 5 1/2 inches when done so it fits in the PFD pocket but you could pull it apart to about 9 inches and not only have room inside for a full kit with a foil blanket and odds and ends but have the two parts still firmly together.the fellow over at Woods Monkey who came up with this had a real brain wave,the combo of cup and a pot that fit and seal means you have a way to make a meal and a drink at the same time and both are good size..but more when i'm done with this project.
