Yep, definately Whitefriars, there was an identical one on a WF website, whose address I've forgotton (on the old pc which crashed). It had a small chip on the inner rim but nothing serious. I gave it another go after a few months and it did go, but still for under a tenner, so somebody got a nice bargain which I don't begrudge as I've had plenty over the years and it's always nice to get a bargain don't you think?
