A Victorian Cream and Milk Can.  Made from tin and with brass fittings these cans came in varying sizes and were used by the dairies to deliver the cream or milk and quite often they had the customers name and address stamped into them.  The brass clip on the back enabled them to hang from much larger churns containing the milk or cream or clipped onto the milk cart.
This one has the name G MILLAR and the address 432 HIGH STREET NORTH, MANOR PARK E12.
