Just found this gem on Notcot…it’s an old skool GPS system! Made in the 1920s! No electronics, no talking guide, no batteries or signal levels, just a good old-fashioned turn of the knob to find your way from one city to another! Check out the link…amazing how this stuff has all been done before. It never took off… (I guess for obvious reasons) how many scrolls could you possibly own?
