Preferably in the UK (but anywhere is fine) I want someone to loan me a Rev J motherboard to investigate clock patch issues. Preferably by someone who has fitted my V4 clock patch already and confirmed issues.

The only way clock patches can progress and fix more issues, is if I have a physical board in front of me to figure out why Rev J clocks are much worse than the common rev D/C boards.

I think @francois has one: viewtopic.php?t=7328

Anyone have a rev J for sale at not silly money? Would even consider a faulty one, again if not silly money..

My 'good' board is a rev D/C and the board I'm working on doesn't have a readable sticker, although I'd guess it's older.

Is there another way to infer the revision?

Not that I know., other than maybe visual matches on boards, in particular related to mods done at factory.
