I have to agree with Lostmind. I think the are both RemLine boxes. But it looks like the top chest is slightly older and has been repainted; note the curved drawer pulls on the chest and the square-ish pulls on the cabinet.
I'm guessing if you sanded the chest you would find a silver-gray exterior with red drawers and bright drawer pulls.
In any event, assuming Lostmine and I are incorrect, you would still end up with compatible and usable chest & cab combination. It looks like a bargain project for your store manager.
