Hi, Jerry,
It sounds like the 4-tab holding stove is the one that's commonly available in sporting goods stores. Here is such
a "pocket" Esbit stove at REI.
I personally am not all that hot on this particular model. I find it a little hard to light, but it does fold up well and being able to put 4 tabs inside the stove is nice. I prefer the little
Tibetan Ti Wing Stove that I profiled on my blog. It's easier to light, more compact, and very light weight, but I know others who don't like the Ti Wing. Each to his own I suppose.
If you get a chance to post a photo of the larger one, that would be cool. Did the larger one have a specific purpose? Is it meant to burn multiple tabs at a time for larger pots?
