"The Cadbury script logo, based on the signature of William Cadbury, appeared first on the transport fleet in 1921. It was quite fussy to start with and has been simplified over the years. It wasn’t until 1952 that it was used across major brands." Source: https://www.cadbury.co.uk/the-story
Some more letters as used in a Cadbury campaign

Note that the _C_ and _a_ are the same but the _r_ is different.
I am not aware of a font based on the logo.
