This larger oiling squirt can is completely made of metal. It is in used vintage condition from around 1950 and made in Italy. High quality piece and instant recognizable design. Not sure if it still functions but it does generate an air flow. Probably would need a clean on the inside to use it again, so sold as a display piece. There are clear signs of use and age (has ca. 70% of the paint). The oil can  measure from handle to spout about 30 cm or 12 inches, marked G700 on the bottom for 700cl / 70ml.
