Hhmmm...!!
Hi Jack, am assuming its a US motor??but that carpet looks rather like a UK BMK classic??
If the motor fits vertical, I would say a Sturtevant or a Richmond, failing that, could it be the one that had 2 nozzles on the front but no revolving brushes??
If it fits horizontal I would say Premier or GE, any more clues as to how it sits??
