They are British Association (BA) threads, you won't find a tap at MMC or
anyplace general like that. Here's a few that probably do have it :
http://www.britishtool.com
http://www.samstagsales.com
http://mdmetric.com/britcut.htm
Sorry I don't recall the BA size offhand and I don't have time to check at the
moment. I did a write-up once on all the "weird" threads on a TR3, but can't
seem to locate it at the moment. If you don't find it by the weekend, write me
off-list and I'll measure.
