Hard to tell - however there are several other style cabinets with lift/fold off oval tops. The legs don't look like the Singer (They are solid on the Singer) so I'm expecting this is one of the other that fits a standard machine.
I've seen some where the top is hinged on the back side, and a leg support pulls out from the back to support the table when it's fully open. I've also seen ones where the table lifts off completely like the FW cabinet does.
This is the Singer one -when you consider the size of the FW, this a small cabinet.
