I am making plans for a model of a lake paddler of 1856, which had british-made engines and boilers. Those were originally made for steamer "Storfursten" which came to Finland 1837. She measured 123x19,4x9 feet. The builder of the hull was Fletcher & Faershell in London. Machinery of 80 hp and two boilers were made by Mauldsberg & Field, London.
I would like to build the boilers and machine to my model, but have no idea, how they looked like. If someone of the members of the paddleducks knows something of the subject, please, let me know.
