The last time it appears new wringer washers were sold ended around 1983...and it seems it's only ordered as a specialty item now or as an used item.
There are relatively affordable washing machines w/options including low water usage. Check the specs of the washers that are offered starting w/Courts...Singer is another company here that shows some of their products online.
To find used wringer washers...you could try the Gleaner & Observer classifieds online or jamaicanclassifieds.com....there's a few other online classifieds...just google. Otherwise, someone down here should just keep asking around.
Good luck..Beccajean!
