All that we have lost...... A sad statement 'it was where the ASDA carpark is now'....... as a retired toolmaker / manager, all these old brands are familiar to me, I have great empathy for the manufacturing history of our once great nation. Good video.
Interesting that you mention similarity of post WW2 tool design. During WW2 much of the intercompany rivalry all across industry was often put aside to achieve a particular goal within a abnormally short timescale, through collaboration. Also, because manufacturing tooling was in short supply a triage system was operated by the ministry of supply on a daily basis, to prioritise company need and issue them accordingly. One example comes to mind in control and issue of milling cutters for use across the UK in those days.
That level of coordination and control is interesting; an untold part of the war story, particularly when high-precision demand were growing in aviation, and materials were getting tougher to machine.
I think the braille calliper has a full 0 - 12 inch range because there are 11 spacer bars (which would measure 1 to 11 inches), plus you have a full inch of motion on the micrometer braille head. So you have the full inch dimension off the spacer, plus the decimal inch off the thimble.
Question: Did M&W eventually change to rolling their micrometer threads? I can see other advantages as well as precision - a smoother thread, potentially worked-hardened, better wearing properties, longer life,

Fascinating video. We only have M&W in the US. Wonderful quality.
I would be really interested in looking at the Hawley collection . Mad about Toolmaking

It seems that machine tooling once occurred in the UK

Sheffield is very lucky Ken Hawley existed! ...... Good to keep great traditions alive.
Interested? I am! But I'm Australia so it's a bit of a schlep.
We're totally missing the transparencies, aren't we? Wah.
