I don't remember what company made the kit(not Monogram), but it was an F-82 twin Mustang in 1/72. It was terrible...and rather than add any further disgrace to my trash can...I got a shovel and buried it in the back yard.
Years later, I tackled ModelCrafts 1/48 F-82, which was worse yet...but my abilities were far greater than when I tried the little one...even made it into the mags "reader gallery"!
