King Gun Sight Co Range Box

I'll apologize now if this is in the wrong forum but I recently bought a hard case marked King Gun Sight Co. I assume it is a range box but I've never seen another. I only have one of the King catalogs and didn't see it listed. It has a removable top tray and it looks like a divider was removed from the lower area.

Is this a range box? ... salesman's sample box? Any thoughts and opinions are appreciated.
