If one examines all manner and sorts of products sold during the war years, you will often see comments in adverts about changes or limtied supply for the duration. P&G did so for it's "white" naptha soap, as did Fels for theirs.
As for diverted and things produced for the war and otherwise not used as intended, it is entirely possible the machine like other things "fell off a truck", or simply went missing. Or, may have been produced but deemed surplus to requirements and never shipped somewhere or purchased by the government.
It is also possible some general, or similar high ranking man got the machine for his wife or bit of fluff as a present. A washing machine sure beats the heck out of a pair of nylons.
Have a cache of Kirkman's soap that was intended to be distributed to military men as they left for overseas,(what servicemen were going to do with laundry soap is anyone's guess), but the case obviously never went as it sits in my larder.
On both sides of the pond, theft and "mis-direction" was rampant, how else did all those blackmarket men get their goods? Know in GB one could be shot for such things during wartime, not sure about in the United States.
As for farming, cannot be sure but think in the UK, gardening was fine, but not sure if large farm animals were allowed, even in the country by priviate persons. After all that would give those in the country an edge on food those in the cities did'nt have.
