Many thanks for your contribution. Without a photo from the original contributor it is quite hard for people, so I just added some images from Hastings Pottery as a visual reference.
The pottery began in 1956 and closed in 1995. The person behind it was Dennis Lucas.
His original partner was Bernard Cotes (previously associated with Orchard Pottery, Addiscombe Surrey, England), but he opted out of Hasting Pottery after only 3 years or so, to start another pottery nearby in Battle.
