Hey AdventureLover - I have one of those - bought it 25 years ago to use as a fondue!! Still got it but haven't used it for years!
All those little bbqs are terrific!! How inventive are some people??
I go camping a fair bit in my Campervan & when 'bushing it' I use my 'gas bottle' bbq ......
This was my "Mark 1" version - I have since upgraded it to a 10kg BBQ bottle & now have 2 the same size! They work terrifically for bbqing meat & stuff - just put an oven rack on top. You can cook your veges wrapped in foil & then cook meat on top.
WARNING! EXTREME CARE MUST BE TAKEN WHEN MAKING THESE! GAS BOTTLES REQUIRE THE GAS TAP TO BE REMOVED & FILLED WITH SOAPY WATER OVER 2 WEEKS, CHANGED OFTEN, THEN ONLY CUT WHEN FULL OF WATER!
We also have a smaller version of the Kiwi Thermette, purely for boiling water (or roasting marshmallows....)

- cooking your marshmallows whilst waiting for the water to boil
Fill it up with water, Just put twigs in the centre hole & the water is cooked in less than 5 mins. The water is contained in a sleeve around the edge of the fire. Beaut little invention!

- nice copper one - will last for decades
Cheerio
