VTG AC Spark Plug Filler Cap Display Advertisement Counter Top Auto Collectible

This is an original vintage AC counter top shelf for AC filler caps such as radiator caps, oil caps, gas caps, and locking caps. It’s in vintage condition and does show signs of weather and wear such as flaking paint, surface rust and patina, dirt/dust, light dings and the door doesn’t want to shut all the way but it should an easy fix. I sprayed some WD40 on the door hinge to get it to open and shut with no problem. It measures 22”x 8”(bottom) 6.5” (top). It only has one display cap for the front and I don’t have the key for it but it pops out the front (can be removed easily). Please, resort to photos for item description as well.
