This brick is in the possession of David Hensley from Kansas, USA. It was obtained from a fellow brick collector who resided in the State of Kansas. It is unknown where the original finder found the brick but it is assumed it was in Kansas somewhere. Roughcastle Firebrick Works, Bonnybridge, Stirlingshire. . . .
Found Craigend Refractories Ltd, Falkirk
I believe this is could be a product of Craigend Refractories, Muiravonside, Falkirk.
I believe J H Sankey & Son, Essex Wharf, Canning Town, London was in the practice of having Scottish manufacturers make bricks with Scottish clay and stamp them Sankey. ( See Weir Castlecary and Sankey) or indeed did JH Sankey own Craigend Refractories.?

What does intrigue me is that this was found at Craigend Refractories site. There were numerous examples and they were mixed in with Craigend Falcons, Eagles and Kestrels. Note the style of brickmarks – all very similar and look at the colour and appearance of the bricks – again very similar.
I have now found 3 x Sankey Aluma bricks at different Scottish locations and each time they have been found alongside other Craigend bricks such as Falcon and Eagle. This all gives credence to these bricks being manufactured in Scotland on behalf of J.H Sankey.
05/02/2018 – Update – Gerry Carty, Rumford, Falkirk used to work at Craigend Refractories and he remembers Sankey Aluma bricks being manufactured there. He is uncertain if they were solely a Craigend product or made on behalf of another company.
See this reference below regarding Aluma
Aluma – Aluma cements are suitable for jointing, coating, and patching in all high temperature applications. They are air-setting, with outstanding bonding properties at ambient and operating temperatures.
Aluma 45 – Ready mixed, creamy consistency air-setting cement, excellent stability at temperature.
John Bramall states – FGF used to be an intermediary owned by GR-Stein (in 1983) – or thereabouts
