This came in at 25 on the Equinox and only quite shallow.
As it turned out, it a bit more corroded than I thought it would be, that said I'm still pleased to have found it.

You're not kidding Easylife, it was very crumbly.
Thanks Tony. I've seen lots of your IDs now and I don't know how you do it.
If only I had a wet Fish to hand.
