Its does have a filter - in the style of an early AEI Hotpoi
Hi there
The filter tray looks very similar to the one found on the first AEI Hotpoint Supermatics which had red "filter-clean" trays.
I'm no expert of the the make, but the machine looks a bit like an English Electric model - one of the UK wringer fans is bound to confirm or correct this. I rather doubt if the filter tray is orginal (again I could be wrong...), as Hotpoint and English Electric didn't merge until the late sixties and early seventies, by which stage filter-clean trays were white.
Chestermike is the man to put us right on this one...
