The teardrop is a classic keyfob shape which has been in use for many years .
The slimline teardrop is the classic leather keyfob shape which was commonly used for British made automotive keyrings in the 1960s and early 1970s .
The classic rectangular shape was used in the 1960s and 1970s through to the 1980s by many of the main British automotive keyring manufacturers .
Some early automotive keyrings were produced with a shield shaped keyfob like this one and it is still to be found in use today.
The torpedo keyfob shape was the first generally available shape in which leather keyrings were produced in any number between the mid 1950s and early 1960s . The split ring is positioned at 90 degrees to the keyfob itself – which can result in the keyring not always hanging flat to the vehicle dashboard when in use- which is probably why this keyfob shape went out of favour and was very rarely used after the late 1960s.
