Here's my overhaul of the Teletype Corp. version. Here's a Lorenz version someone else has. Here's Bletchley Park's set, with the crypto unit and the teleprinter.
After I got my first Model 14, I had the paper tape they need made by a company in China. The minimum order was 500 rolls, so I sometimes sell paper tape to museums. (I tried US manufacturers first. Either they didn't want a small order, wanted a very high price, or the edge quality of the paper was so bad the tape would jam.)
Now that's a Baudot/ITA2 character set variation I haven't seen. There's already USTTY, ITA2, weather symbols, fractions (⅛, ¼, ⅜, etc., for stocks), versions with £ instead of #, and versions with a pilcrow. (¶). But I've never heard of a double lightning bolt symbol.
Unicode has a single lightning bolt (Stack Overflow cannot handle this) up in the astral planes with the new emoji. But no double lightning bolt. I suppose a request for that now has to go into the Unicode consortium.
TNMoC has some WW2 machines (most importantly Heath Robinson and Colossus) but they also have pretty much every other computer imaginable, with some of the proper historical stuff actually functional, and more BBC Micros than I've seen since school.
