Turns out its a 22mm yamaha spanner. Rubbed some oil in some hopefully it won't rust back up.

yep works nicely cheers! i think the courier had kicked it around a bit as the inerds were loose in the casing but putting it back in its retaining slots seemed to secure it well enough. Has a old-fluorescent tube hum going on. didn't register much output over the spanner-tank but the needle went to 2 on a nearly charged car battery so I think its ok.

The closer that the anode and cathode are together the faster it works. Also bigger sacrificial piece the better. I've seen 15amps going through mine.

 

Also if you derust any bolts stronger than grade 8.8 and want to reuse them need to heat them in the oven for an hour or so at 200c to prevent hydrogen embrittlement.
