I've seen boxes on CL which look similar to yours. They are Stack On boxes but just going off the pictures.
They seem to be about same size, drawer pulls and pulls are low on the drawer like yours. Many boxes where made by one company and rebadged under different names. Are there any holes where a badge could be missing? Best bet to to take out into the sun and look close. Even if know where to look the date stamps can be hard to see. How much did you get if for?
