TEA oil pressure gauge

I don't suppose your question on old British type threads would be directed at us old British types would it?

I have a 106kb Excel spreadsheet which gives details of thread pitches, sizes, ODs and designations which I can email you.

I can also scan and send a useful inch/metric conversion chart which gets you from mm to fractional inches, or vice versa.

Let me know.

Thanks,
Jim
