No, that’s a lid of my second 6 gallon milk crate tackle box that I made. It cold be a fillet station in a pinch I guess. I wore out th last one after 20 years and now use this one. Very versatile and you can see from the holes that I had a seat on it at one time. I haven’t cleaned a fish in months, maybe even this year. It does my attitude good to go and visit with them sometimes.
