There is a W&W D9 treadle machine on the GW auction in MD. So far only one bid. Both the machine and cabinet have issues, but are fixable.

Just my suspicion but I'll bet if it goes cheep it will end up repurposed into a table or something else equally offensive.
So if someone want's one of these, here's one to rescue.
