Full disclosure, I did not have that as a kid. Honestly half the reason I wanted to set this stuff up in the basement was so I could see it!
Back when I was renting a house in college, the people renting the house beside me were moving out and asked if I wanted "this GI Joe battleship thing that is missing some pieces?"
"Uh, duh!" was probably my answer. I quickly took whatever big chunks of plastic and vacuum cleaner box of parts it was and stuck em in a corner. Then when I turned into an adult and moved out, it landed in my parents barn, and has been there for nearly 20 years. Last night was the first time I had ever laid it all out, and I quickly realized that it was much more complete than I knew. It even had the instructions and the sticker pages (though 95% of them were already installed). My oldest and I were thrilled to see that it had all the deck pieces and the entire bridge. There are a few broken tabs and missing gun barrels, but I'd say its about 98% complete.
