Leonard (Len) Street, Rosecraddoc Pottery

I love connecting long forgotten potters to potteries. The latest is Len Street and Rosecraddoc Pottery (sometimes called Rosecraddor because of the old fashioned font used on the boxes, which makes the c look like an r). The Pottery is listed on The Digital Museum of Cornish Ceramics, and was based in or near Liskeard, Cornwall, but no potter is mentioned. The pots are mainly sets of small moulded terracotta butter dishes, with farm birds and animals on the lids. They have a flower (a rose) and UK stamped on the base. Then I came across a wall plaque, stamped on the back: Leonard Street, Wheal Cottage, Prideaux Road, St. Blazey, Cornwall – using the same font, clay and decoration as the Rosecraddoc Pottery.
That led me to a PDF online, of a pamphlet titled: Livestock – The Backyard Dairy Book, published in 1972 by Len Street with Andrew Singer. The ‘about me’ page said that Len and his wife June had been homesteading in Cornwall since the mid 60s. They had built one house and were in the process of building another. They kept livestock, selling butter and cheese, and Len made pottery house signs decorated with old fashioned butter prints. They had featured on the BBC’s ‘Man Alive’ series, talking about homesteading and self-sufficiency.
It’s uncertain where Rosecraddoc Pottery was based. There’s a Rosecraddoc Manor near Liskeard, which is now holiday lets. Maybe it was based in the grounds c.70s-80s?
