campagnolo cassette - unusual lockring

[blue_october]

Hi everyone, I want to remove my 10 speed campagnolo cassette (12T-25T) but it doesnt have the standard lockring. Below is a link with a photo:

Does anyone know what tool will remove this lock ring? I've searched online and been to a few bike shops and still no luck.

Thanks for taking the time to read/help.

Much appreciated!

I've never removed a campy one but you probably know they need a different one from Shimano.

Edit: The Photos just come through get a 2nd opinion but that one looks different again!

Looks like a bike shop job. Get a standard Campag lockring while you're there

You need a pin spanner

It shouldn't have got too tight (unless it was screwed on really tight to begin with) so a two pin spanner may well get the job done.
