The chrome-moly (Chromium & Molybdenum alloyed steel) I know has the SAE designation "41xx" as in 4140 and 4130.
The 'K' is for 'killed-steel' which describes a process when making the ingot for better quality. 1044 SAE designation describes a plain-carbon,that is no significant alloys steel with 0.44% carbon analysis. I know it is great for basic tools like hammers and smith's tools, but would think it makes an ok, but unsophisticated, spanner.
Read the wikipedia entry for better explanation; https://en.wikipedia.org/wiki/Alloy_steel
Of course, we don't know what exactly Mr Siddons was using that particular batch for... maybe broom handles?

I believe most spanner steels use an alloy with vanadium in it... Vanadium I read controls grain growth during the manufacturing process...

A fine grain tool is going to be better..

Great video, thanks for sharing.

Interesting on cultural grounds also, not to mention dress, and Health and Safety standards.

And, ... is that a Leyland Badger truck?

(At least the truckie was wearing safety thongs).
