Probably asked this before

I bought an Arc LS off E-bay a while back with a bar metal twistie, and you could also screw the head off to adjust the jumper to change the current. The head was HA the twistie was bar metal and the middle was quite a rough metal, beam profile not fully centred but nicce and bright, it says first run on the lettering. What exactly have I got?

I think I saw something like that before being offered here and on ebay, I remember people said it's put together using Arc grey parts, so it's not an offical Arc product.
