50s vintage metal storage box for records or reels, travel case with handle

50s blue metal storage and travel case for records, or reel to reels? It's 8 3/4" x 8" x 7 3/4" tall over the exterior of the box, with built in metal dividers on the inside.

This is in pretty nice condition, very little rust, just a few light scratches and marks from marker ink. We love the color and the box bag shape, like a train case!
