According to Harley Marshall, this is likely to be a firebrick for a ship’s boiler.  The hole in the block is recessed for about 3/4 of the block depth. At the bottom of the opening, there is a further opening to the left and right. This opening is to take the head of a long bolt. This bolt has a special head with flanges that you twist once seated into the opening so the flanges enter each of the gaps at the side. The bolt is then entered through a hole in the boiler wall and tightened pulling the block in tight to the wall. You, therefore, have a firewall lining but with no bolt heads sticking into the boiler itself. This was an Admiralty Patent. (AP – was often an abbreviation referring to Admiralty Patent). Apologies to those with a technical head for this very non-technical explanation but I hope you get the idea.

The BW possibly refers to Babcock and Wilcox who made ships boilers – Click me
