Unfortunately, it doesn't include the IRC "BT" series of resistors, used heavily by Philco and other manufacturers in the 1935-42 period. They are tubular insulated types, but are coded with the body-end-dot scheme. Another type which turns up occasionally is the Micamold insulated resistor, made in both carbon and wire wound versions. Those have the colors arranged in a series of dots, with one dot shaped like an arrow to indicate the direction to be read. They look like mica capacitors, but their bodies are very slender.
