Very nice work there.
I have a small nesting stove similar in design to yours; I got it as new surplus from the War and Peace show some years ago.
It's about 4 1/4" (11cm) diameter and 3 1/4" (8cm) high when packed. It is made from chrome plated brass I think. The burner is meths I assume, with a wick instead of Trangia type jet-holes.
I think it may be French or Belgium army surplus. At a guess it may be from the 1930's ?
I'll try and get a picture in the next couple of days if someone could post it on the thread for me.
