nice little machine you can find more info by searching int the top of the screen about an inch below log out there is a white space - type in Singer Spartan - then hit the magnifying glass and see what comes up.
It is just a heavy little 3/4 sized machine - it was considered a portable machine so usually found in a case - some times found in a cabinet. Kind of a kick start - here is link with info about 3/4 size machines:
