vintage snap on tool box identification

[gjwilliamsjr]

Trying this again. I picked up this snap on tool box at s local auction for $20. Can't go wrong for that price. I'm trying to identify which model it is. The bottom cabinet is wired for lights. Any help would be greatly appreciated. Thank you

Found the top box. .k-55 (thank you zkling). Still trying to id the bottom cabinet. It is wired for lights and has *custom deluxe" emblem on the back. I'm not sure if that came with the box or if it came off of a car. It belonged to someone who worked for Patrick air force base in the 50's.
