I've seen this before. You have to love that chart that tells you how to figure it out. And don't forget to lay it on a flat and level surface to read it.

Doing a bit of digging, there's a short paragraph in A Prismatic Derivator. Nature 129, 126 (1932) that describes it, and lists the parties that produced it. That could give you a lead to track one down. I couldn't find anything else easily though.

I intended to record this talk while I gave it, but something went wrong so I had to re-enact it in my hotel room afterwards. That's why I sound like I'm talking to myself. For an expanded version of this talk with some more background on the IRV ("ranked choice voting") system, see here: kzbin.info/www/bejne/i6DcqaeAmKyfisUsi=ya5d5l_aGVWSTgJY

The 2 minute discrepancy is likely due to the magnetic North Pole moving over the decades. It’s moved a long way in the last 70 years in particular

In the pre-computer age, page layout in all graphics printing was a HUGE part of the advertising-printing and related industries, they had lots of tools to transform and rescale proportions for magazines, posters and billboards, all very different size jobs!

There are still a few different kinds of graph paper available. Probably the commonest are 2/10/20 and 1/5/10 mm. in A4 pads with margins of 10mm. left and right and 9.85mm. above and below; but 5mm. squares right to the edge are also fairly common (and one of my favourite programming aids; when I first learned about computers, you really had to have some things sketched out on paper before you even switched anything on, and even today I still like to have an idea on paper before I type anything into my favourite text editor). I've even been known to write PostScript code to produce special-purpose worksheets such as 1:1 and 2:1 copper strip breadboard layout sheets showing where the holes are and where the tracks run underneath, so you can draw on parts and park track cuts. I even made one for calculating PDUs for SMS text messages, although you are probably only likely to need that if you are doing low-level debugging on mobile telecommunications kit.

This may not be a great lead, but ... I'm currently watching the 1960 movie The Apartment. The main character, played by Jack Lemmon, works at an insurance company and uses a Friden STW 10 mechanical calculator (I believe), as do his coworkers on the floor. The machines are shown right at the beginning of the movie, and again at the 20 minute mark. (Maybe elsewhere too.) It's on-demand at PlutoTV (a free streaming service with commercials).
