That’s a good idea. Thank you. I’ll try that.
I heard back from the Director of Archives and Collections at the Petroleumn Museum today. She said that the drum appears to be from the time period 1870 - 1911. Standard Oil was broken up in 1911 into different companies. She says that the "Standard Oil Co." and serial number on the top support dating the drum to that period.
She said that her museum has a similar drum from Magnolia Company (later Socony-Mobil). Their drum came from an old gas station and was used to pump oil and gasoline. She thinks my drum had a similar purpose.
She isn't able to give me an estimate on the drum's value but I've asked her to refer me to someone who can appraise it. We'll see what turns up.
Constitution Day - Do you know anyone in your industry who could appraise the drum?
