It looks like a late 50's KR-352 roll cab. I think someone replaced the original badge (should be chrome?) with an earlier 50's style badge, but that was around the time of badge and handle change over, so..... It maybe original.
Price wise, kinda area dependent. For me I would list it at~$150-175. Take ~$140.
Buying I would pay up to $100, depending on in person condition. I am not a snap on collector. It is a nice box, but it does not have much storage (only 3 drawers). Just my 2¢

Do you have the lower cover for it?
