Attached is the best images I have of the Micro Torch. I believe they're the same photos that James posted: note that they seem to be from 2 different ZF1s, based on the extended/layered white tip and the orange in the hole of the 2-part base on the ZF1 with the White Background.
There's a few "micro torches" on ebay that are "close" (most orange, made by Chicago Electric/Harbor Freight), but they're not quite right: they don't have the 2-part extended base (next to the main body) and have "tube ribs" that are "ridged" not smooth like the one that James shows.
The closest I could find was on Amazon: Blazer GB4001-02. It even has the white end (whether it ships with that, who knows: you never know if you're going to get exactly what's pictured on Amazon or ebay). Here's the link (currently @ $33):
Let me know what you think.
