Cycle myth is correct.

Brass tag was originally a Ford asset identifier. There was an asset number stamped on the tag. Originally, company cars were assets and had a tag attached. The tag on cars could be either a rectangular tag or a disc. Cars that were fitted with a brass tag had generally unrestricted access in and out of the plants security gate. Cars fitted with a brass disc were generally employee lease cars and access to plants was restricted. At some point they stopped stamping numbers on the tag, and then eventually got rid of the tags too.
