Correctamundo!

Then there's "Nuffield's Mad Metric" -- Morris (owned by Lord Nuffield) bought an old (previously French-owned) Hotchkiss engine plant in Britain some time after WW I. With the purchase they got a lot of old French tooling. The French at that time were using a variation of metric (almost, but not quite, the same as current JIS). However, all the Morris & MG line workers had British Standard tools, not metric. So Nuffield had fasteners made with old French metric threads but British Standard heads. Try finding those at Fastenal!

This is very interesting, im glad i have no plans to mess with old british stuff!

I bet you there are enthusiasts who order up custom fab. bolts and nuts.

If I were rebuilding old stuff with Wentworth, I'd probably do that and sell the extras. For a guy who needed just a few, you could command a decent premium and cover your own costs.

Not to mention (from what I've read) that there were among, certain European regions (crossing over lines in France and Germany) local standards (non-metric) for fasteners. But that mixture of threads and heads is certainly one of the most interesting combinations I've read about.
