County Car Badge 1950's/60's

This is a county car badge from the 1950's or 60's and belonged to my father in law - my husband remembers the badge on various cars his father owned. � However, we cannot work out which county the badge represents, but possible East Sussex.

It's in fair condition as you can see from the photos, and includes the car fixings. � The photos show some speckles to the chrome and general wear and tear to the enamel.But considering the age it's a pretty good badge, and probably quite unusual.
