Diamond shape

Found at the old James Dougall works, Bonnyside, Bonnybridge.

Unidentified maker.

Find location would suggest Scottish origins but …

Considering the find site, this may well be a James Dougall product.

It may also be an early Dyson Refractories product. They took over the Bonnyside Works from Dougall and their emblem, which appeared on many bricks, was a diamond.
