10/10/2019 – Further research and information from Jean Bear, USA reveals that this brick is most likely of American origins. Jean states – “I have found several of those firebricks in southwestern Pennsylvania, USA, and know that in Curwensville, PA and Clearfield, PA they were made by Crescent Refractories Company (1922-29) or North American Refractories Company (1930-75) after they bought out Crescent. Often, though, firebrick manufacturers are hard to determine, because as smaller companies were bought by larger ones, the same molds were often used.”
