Early RCA Mechanical Pencil
with built in Dog Bone Resistor Color Code Chart and Magnifier

These "RCA Service Engineer's Pencils" were given out as an incentives to dealers for selling a number of RCA "World-Wide Antenna Systems" or vacuum tubes. This one has a built in Dog Bone Resistor Color Code Chart and a magnifier on the end for reading small component numbers and values on a schematic.
The first band on the chart is for the resistor band color, the second is for the end color value, and the third band is for the dot value (number of zeros).
Several versions of the RCA pencil with different features were given out as sales incentives.
