The brand appears to be Parasene. It was the cheapest in the shop, but
also the one which claimed to have highest heat output at 4kW. (The
primus/sievert one was a similar price, but seemed aimed at smaller work,
and it claimed 2.4kW, so thats why I went with the Parasene one.)

I'll let you know how she 'blows' when I've knocked those burrs off.
