High Stability resistors

Special "High Stability" resistors with an extra pink band (sometimes called "salmon") to indicate their superior quality. From left to right, a modern 4.7kΩ for comparison, a 68kΩ, a 3.3kΩ, two 56kΩ, a 220kΩ and a 2.7kΩ. All are 5% tolerance (gold band) apart from the 56kΩ, which are 2% tolerance (red band). The modern resistor is a metal film type, but the older ones are carbon composition. They were wax coated for moisture-proofing.
