This is a really nice electronic schematic symbols chart that will come in handy for hobbyists who work with vintage electronic equipment. Not only does it have component symbols that a modern chart (this appeared in a 1942 issue of Radio-Craft magazine) would not likely contain, but it has three-dimensional sketches of each device. For example, vacuum tube symbols show the tube outline, its socket configuration, and the pinout. If you get nostalgic for some of these old parts, some of them like the knife blade switch and ceramic light socket can be bought a many hardware stores or online. It's too bad the chart is not in color because it would make a nice picture to frame for a decoration. If anyone with an artistic bent feels compelled to colorize it and send it to me, I'll be glad to make it available to visitors.
