Probably something cut down decades ago. There is no need for those huge handles for a can that only holds 2 gallons.
I agree most all five gallon had one handle Ten gallon had two handles. Never have seen one with fill TAG most are stamped. But great item to strike up a conversation. Maybe a can made for Little People.
The Ellisco five gallon Endurance and Super Service side rack cans had 2 handles. You could order a 5 gallon Ellisco can with a single handle spot welded to the can top, an offset neck, and a swinging handle to hold the can while pouring.
Based on information provided by the seller (the 2 gallon can has not arrived yet), there is a 2 gallon "Fill to Here" brass tag soldered inside the neck of the can. I have searched all over the Internet and not found an Ellisco 2 gallon can. If the seller misrepresented the can, he will hear about it from me.
I received the can today. It is a 2-1/2 gallon Ellisco oil can. The Ellisco ID tag is made of tin, not brass. I have never seen an Ellisco oil can with a tin ID tag. There was never a fill mark soldered inside the neck. I have been unable to find an Ellisco 2-1/2 gallon oil can by searching the internet.
