Long lost stove

My step-father has this neat little colapsible stove for solid fuel. We think it was a military issue item at one time. The thing is wicked light and works great. He got it years ago but despite our search everywhere (on-line and in about every Army/Navy store we come across) we've never found another one.

A friend who works for GE found the patent on it and below is a description.

Has anyone seen one of these and know where I can get my hands on one.

Thanks in advance for any assistance.
