As my mother in law digs through the house looking for things to give away (because she has a hard time throwing things away) she came across this leather box that had belonged to my late father-in-law. I assume it's from the '70s. She guilted my wife into taking it home to me. Wasn't too interested and it sat in the garage for awhile until one day I realized I could put it to other uses. But I still don't know what it was for. I know it wasn't for what I'm using it for now. I'm not sure what the slots inside were meant to fit, or the space inside the lid. Anyone recognize it? No label, google image search came up useless.
