Thati s a very nice machine and cabinet - can you tell if a stack of drawers is missing from the right side?
Use the funds you didn't have to spend to find the parts to complete the cabinet. I've seen the drawers (if they are missing) and top on ebay quite often. BTW- the Singer lids have the same diagonal crosshatching on them as the front of the center drawer - so that is what you'd look for if the seller does not know what it came off of.
That machine and cabinet is way too pretty not find the missing parts.
