Found at Stein Manuel Works, Whitecross.
Harry Baird used to work at the Manuel Works, Linlithgow. Its somewhat confusing but a particular brick with say 50% alumina content may have an international code and also a specific code as per the individual manufacturer. He gives the following as examples of brickmarks and what they could mean
RO – code for a specific design or customer. His recollection is that RO stands for the customer in this example and he recalls it may be The Gary Works, a major steel mill in Gary, Indiana, on the shore of Lake Michigan – WIKI
XX – signifies an International standard for Alumina content
144 – Code for where the brick fits into the design / structure plan in question
ND – Nettle Dense
