Hi everyone. I just picked up 3 of these oil dispensers. 2 are Conoco Super Oil and the third is this smaller with "WAYNE" embossed on the large lid. This is the one I'm going to restore and keep as it will go good with my old Wayne 515. I'm new to this area of collecting. Can anybody inform me of Wayne oiler history? I find lots on their gasoline pumps but little on the oilers? Any help appreciated. Thanks in advance!
