I ran across a couple cans today. They are weight and measure cans, 1 gal and 5 gal. They were used to test gas station pumps to make sure of the measure and volume. They had a tag from the Minn weight and measure. They also had travel cans that they were stored in side of during travel to prevent damage to the measure can. I have never seen these before, what are they worth? He offered to sell them. One had a decal Butler.
Thanks
