This treadle is a "parlor cabinet," with gorgeous burl wood grain featured on the smooth front, with four mitered panels, and edges with wrapped straight-grain.
It opens to reveal three drawers, upper and lower are fixed and the middle one swings out. There is a wood cover over the iron treadle, that simply lifts up and snaps into a clip on the side when in use. The belly pan has some damage, but is functional.
The front swings out to support the leaf. Note treadle cover is up in photo below.
This cabinet has a feature that is common on Pfaff treadles, I've not seen it before on a Singer, and that is a pin cushion built into the cabinet. This one is in great shape.
The machine is one of the later-style 215Gs, with a profile much like a model 185, except it's full size. It looks a lot like a Singer 15-75, but it has a feeddog-drop lever at the base of the pillar, and it has a 1-o'clock bobbin assembly.
Turns out this is an exceptional machine for freemotion stitching, on a par with my Necchi BU/Nova and also a Singer 115 I once owned, which was the best Singer for FM stitching I've had until this one. Makes a beautiful stitch and is quite forgiving of jerky movements.

The inspection plate on back is different from most American-made Singers:
It has a solid handwheel, and a motor boss:
