Scotland's Brick and Tile Manufacturing Industry

I am trying to create the most up to date list of Scottish Brickmakers and Marks so please send me links or photos of any Scottish bricks or variations that do not appear here so that I can add them to the ever-growing list. Please feel free to suggest amendments or point out errors. Please use the contact form.
All donations of bricks will also be gratefully accepted I will arrange uplift.

I am also looking for contacts around Scotland with whom I can liaise with regard to locations for picking up bricks and local information.
