I acquired this scotch boiler and am planning to use it to power a Stuart Sirius. It is 9" long and 5" in diameter. I contacted someone who had a simular boiler in a model I saw on a steam forum; he believed it was purchased from Coles' Power Products. I managed to locate a number of their catalogs (1939, 1950, 1963, and 1985), but none of them pictured this boiler. Does anyone know who built it? Also need to find a ceramic burmer for the 2" ID burner flue.
