I've inherited five round Ellisco 5-gallon gas cans embossed "Shell". One appears to be a different model from the others. They have varying amounts of the original blue-gray paint. I was surprised to see Shell cans not in one of Shell's colors. I guess that wasn't Shell's practice in the early days?
I also have 11 Davis Welding 5-gallon oval cans. They are yellow and came from a Shell facility but are not embossed with a company name. The can in the attached photo is typical of the amount of paint remaining.
I'd be interested to know the value of these cans. Thanks.
