hi everyone, i recently acquired a stationery engine that has been asked to be restored how ever i can not identify what model/make it is, the base resembles a Jenson engine how ever the engine and boiler aper to resemble Mamod along with the steam chest and valve gear, any help will be greatly appreciated

I’m currently building a Stuart Sirius, but I’m not sure how best to tackle the crankshaft? Any thoughts are greatly appreciated.
