Well, made me look at the one I have. Turns out it's an Antex CS18 240v with a 2.5mm chisel tip.

Had the thing for Donkeys years and never knew, as the hanging hook was covering the name. Turns out the hook can be rotated AND the chisel tip can be extended along the heating element! 

If you have an Antex keep it, it's a brilliant iron, mine had the same tip on it for about 25 years and has seen plenty of use (my 2 Wellers need permanent tip fiddling).

PS: If you fancy buying yourself a Christmas present, Antex also do soldering stations.
PPS: For the work you do, please do not use acid flux, ever.
