Mathew, was the polystyrene block an original fitting or an unofficial modification, do you know? I've had machines shed their pulsator belt when being moved on their back or front, not a problem for us tinkerers, but inconvenient for the original owners, so your theory also makes sense.
After I got my HMDL I also picked up a W7002, which was the last power wringer machine. It was also the last model with a fixed motor, otherwise the wringer belt would slip when dealing with bulky items, and the wash is much more torquey, three pairs of jeans are not problem, and it's also better at dealing with stalling, the wash bobs around until the load starts to turn again. Thinking about it, the W7002 out-turnovers my HMDL with the modification, tomorrow should be washday so I may put some styrene in before then.
Suds - if you try it, will you let us know how you get on?
Si - like Lance said in another thread, Empresses are very common compared to most vintage washers, so you can afford to be picky when looking for one - I suspect that with a bit of patience you could pick one up for under a tenner! Like Al says, not all of them came with a heater, and some of the older ones might not have an emptying pump either - they just have a tap behind the wringer cupboard door, you can see it above the wringer in the 1947 advert below. So unless you can route a hose down a drain or outside, you'd be stuck emptying out gallons of water by bucket - no fun!
