Not sure how this fits. I've gone through lots of stoves and still have most of them, Coleman Peak 1, Svea 123 & 123R, Optimus 111, et al. . . latest stove is an MSR Pocket Rocket which is in the Get-Home-Bag.

The one item that I've had and used since the late 70's and is now in my truck kit is an old Revere Ware all copper kettle. It saves a lot of fuel when heat transfer is efficient and the vessel in enclosed. Unfortunately it's too big for the GHB which has a small Ti kettle stuffed with an assortment of goodies (not a classic).
