 clean one. We were taking those old copper ones and cleaning those. You'd spend that much money cleaning them. And they were perfect. They would take the tanks off. Exactly. They did a great job. But if you were to buy one of those, that was like a $500, $600 rate. I'm going to check on that because I bet you there is somebody still around doing it industrially and we just don't know about it because we don't do it anymore. I'm sure it's industrial. Maybe every one of them is doing industrial. Does that help you out there, Art?
