Unidentified brick-pips and squares

Found by Eddie McLean in the Glasgow area.

Unidentified maker but highly likely to be of Scottish origins.

It is enamelled in white to one side.

It is stamped with a circular mark and an unknown number of raised pips or pellets – at least 7 and probably 10.

The reverse side has a double square design.

These marks are similar to the marks on two other known white clay and enamelled building bricks.
