I bought this sign on ebay mainly because I am a sucker for cobalt blue and white signs but also because I happen to have a pump this would attach to across the top with a bracket. My question is this truly a Pure oil sign and what time frame was it used? And what does it mean "no stamps"?

eBay number. 310824776963
