As With Many Other Vintage Large Appliances
Worth and or what someone is willing to pay will vary greatly.
Persons have tried to sell nearly new or at least gently used wringer washers, ironers, early automatic washing machines and so forth at dear prices, only to have no takers. Others have tried nearly giving the item away with the same results.
At current exchange rates would say nearly $200 to over $300 (changing pounds to dollars), may be a bit generous. It is all going to come down to how much someone really wants the item. Have seen almost new out of the box Speed Queen wringer washers languish on eBay at nearly $50 with no takers.
