Two round tall beer looking brewery type water/liquid tanks with steel stands that are 250 gallons each.
The tag says they were used for some kind of water solution it looks like.
These are $100 each 
Two people can lift these but they are really sturdy and somewhat heavy.
6’8” tall with stands and the tank is 6 feet tall
They are 31 inches wide
The tag says they are:
Nom. Diameter is 2’6”
5’3” Nom. Height
Made for something water related and all fiberglass and the inside looks like it was lined with some special coating.
Look at the tag for more details.

Call me if you want these..
