I have one just like it, it was my grandmothers, I was told at one time it was a treadle made over into a portable, wouldn't want to lug it very far, it's quite heavy, still works, only thing I think may have been replaced is the cord. Wanted to sell it but no one here wants it. If you look at the plate on your machine there is a number and some letters I think, if you call Singer they will give you the exact date and where it was made. Hubby made a great find.
