Since it has no distinguishing marks, the only clues are the parts themselves. Department chains often commissioned planes from stanley, sargent or miller falls. That rear tote looks like some miller falls planes I have seen, but who knows?
It is up to you how much work you want to put into bringing it up to working condition. Some will say it isn’t worth fixing, others would restore it to mint. I personally like the challenge of giving old tools a shot at a second life. Some become everyday users and some become paperweights and some are in between. If the sole is relatively flat it might be worth fixing up to see how well it works. I was given sargent hercules no 5 plane. I probably would not have bought it myself. I decided to clean it up and found that despite its light weight it was a passable jack plane.
