I was searching for a locking filler cap for my Jowett Javelin. Unsurprisingly for a relatively rare car, it's often difficult to find in parts listings. However, I was advised that the 1960s Ford Anglia had the same size fuel filler neck, so I ordered the cap and it fits perfectly. It seems well made, the locking action is smooth and precise and the chrome finish is well applied, so it should be durable. I was pleased to have found it.
