Bing? Dynamo 2-4v
This is a substantial old dynamo. There is very little info out there about it but I was suggested at a local steam toy exhibition that it is possibly a Bing dynamo. It is not in working order but, with a little soldering, is probably fixable.
The Bowman "HIPOWER" Water Motor
The Bowman 860 Water Motor is a very unique and rare little machine. It is a miniature water turbine that allows you to run your steam accessories from your kitchen tap. There is usually a rubber seal where it fits on the tap but this is usually always missing (probably long perished). It is in perfect working order. More info here.
