Looks like the hook in the lid might possibly fit over the wheel.
Sometimes these machines originated as hand cranks, which were later converted to electricity by adding a motor. When this change is made, the cover sometimes no longer fits the machine.
Be very careful not to scratch the machine; good cosmetic condition adds a lot to the value.
Looks like there is a "hook" in the base that you can move so you can tip back the machine. The base was used as a storage container, and you might find some accessories in there. If the base is not big enough to hold the foot control, then I also think that the hook in the lid is for the foot control. Does the foot control have a button? That is the old kind. If the foot control was switched out to a newer type, that might not fit the original hook.
