I've got a Swiss mess kit of similar design.It is stainless steel and does not have the internal pot.But it does have a Trangia alchol stove and a fuel bottle in it.The kit nests into a wind screen/stove assembly.It is a great design worth more than the fifteen dollars I paid for it.The Trangia burner I've seen go for $20.00.I found it in a Army/Navy store and I'm sure you can too.These are built to last a couple of life times.
