Hi !

I use rectangular Trangia mess tins for some kits, but they would be too small for your kit :

the ones I find here are :
-- 6.50 x 3.54 x 2.56 inches , weight = 5.64 oz
-- 7.87 x 5.12 x 2.75 inches, weight = 8.64 oz

May be you could use 2 tins to put all your gear :
* one for Fire/Signaling/Water/Shelter !
* one for FAK/Food/Misc. tools

And they are mess tins, so you can use them to boil water or cook ....

You can put quite a lot of gear inside those mess tins (see this thread )
