Bryan Donkin horizontal engine

Large twentieth century horizontal engine by Bryan Donkin, in good unrestored condition. It turns over freely, in a fit of enthusiasm when it first arrived we plumbed it up to our Stafford test boiler which ticked it over nicely in the gloaming one evening outside the workshop - there's a short clip of it running here.
