Old 5 gallon oil can

I just recently bought this 5 gallon oil can for 15 dollars at a local flea market. I was told it was from the 20's-30's. I didnt know much about it and wondered if it had any value. It still has a bit of oil in it and what looks like a yellow paint job but it is all worn off you can still see a little of the paint in the pictures. I dont know if its original oil.
