Royle (Roy) Saywell, Old Forge Pottery, Puttenham, Surrey (anvil mark)

 
Via the Puttenham Study by Mike Peer:

A lovely picture of the village forge around 1920 and shows the blacksmith George Heath with his son, John Heath, in the centre and their assistant. The forge is now a private house on the north side of the Street opposite 'Rodean'.
The building looks much the same today with a large low stump where the old tree stands. In the 1950's the building became 'The Old Forge Pottery' as the business of  Mike Peer's uncle Royle Saywell who later became the chief potter at Grayswood Pottery near Hindhead.
