Dandelion

Close up of a dandelion seed head.

I had a few answers to last night's little puzzle. KenPetch and Alasdairb were quite close on the milk bottle theme. It is a Graham-Enock milk bottle washer, a clanking steaming beast that always amazes me that it doesn't break more bottles than it washes. A labour intensive machine that has to be loaded and unloaded by hand, nice job on a cold morning.
