Vintage Hastings Piston Rings Advertising Light Up Sign Auto Parts Cabinet

This vintage Hastings Piston Rings advertising light up sign manual parts cabinet would of been in an auto parts store and used to store parts manuals. It is made to light up in both the front advertising panel and the back where the clerk looks up the parts. The front panel light is not working so it probably needs a new bulb and it has a slight bow to it. This would display great on a shelf with the Hastings Tough Guy showing in front and it measures 50 1/2" long.
