This is a set of a lidded serving dish and sauce pot from the Johnson Bros. "Haddon Hall" series. ● This product is from Johnson Brothers, a long-established British pottery brand founded in 1883. ● This series is believed to have been manufactured around 1960. ● These are old items and have kiln marks and scratches on the back. ● The backstamp also has a patent number. ⭐︎I think this is a valuable collector's item because the kiln is now closed⭐︎ Thank you for viewing.
