Dear Dave,

I know this company has been mentioned before, but it may be worth looking at?
Tracy Tools in the UK ?
www.tracytools.com
I hope this is useful.?
They sell a wide range of odd size taps etc., as well as the usual ones. (I’ve used them for years.) They always seem to include their latest catalogue, which I find useful.
