I don't know what the machine is, but it's almost certainly agricultural. And it was outside The English Barn, a listed building in Thatcham, Berkshire. The barn's still there - redeveloped - but the machine isn't. I painted it in colours I rarely use, avoiding white until the last few knife-strokes. There is quite a lot of a so-called 'Flesh tone' made by Reeves - it's the sort of lurid peach colour that every potential bridesmaid dreads - which made a good generic "light" in mixes.
A couple of late in-progress shots:
