Cool old aluminum tank. I think it is aircraft since it came from a yard with a lot of other airplane parts. Clear inside. Seams are sealed with some type of epoxy like goop. Looks to be made from 16 gauge. Measures approximately 16"W * 27.5"L * 13"H. I guesstimate the volume is approximately 18 gallons Its got the look. Can deliver to the LSR.
