Didn't know could get them here in Australia. They are insulated, double-walled stainless pots that make ideal mash tuns.
These things have taken the UK homebrew community by storm recently, and only in the last few weeks I noticed the yanks on HomeBrewTalk have started to get on to them. People are also using them as fermentors (by adding a heating/cool coil) and as electric boilers (by adding a heating coil)
Seems they are made in Germany and sold through ebay Germany and ebay France. A few UK home brew shops are importing them for local sale (eg.

The same German HBS is also making gorgeous laser-cut false bottoms for them like these -

They come in a wide range of capacities - some with taps, some without. The tap and custom nipple (that connects through the double skin) are chromed brass. The poms are often swapping out the tap for SS ball valves ( see the video here for how its done

As for the pot on sale on GumTree, be aware that it is described as "BRAND NEW. Never been used".
However a look at the pics shows what looks like someone has had a go at adding another hole in the bottom :

And the only inside shot has the hole covered up with a wad of cloth or something (hiding a dodgy weld job?).

I've emailed the seller asking about it but no reply as yet.
