BRICKS A-G
ADAMANTINE CLINKER REGD - I'm sure we've seen these before somewhere...
These were produced at a brickworks north of a village called Little Bytham in the South Kesteven district of Lincolnshire. The Company was established in 1850 and was active well into the early 20th century and made small, high-fired paving bricks, called "Adamantine Clinkers" because of their hardness, for paving stables and other floors.
