Yep that head/helmet is all made as one solid piece. It's the same one used on the Sky Patrol Airborne recently. There is no way of making it removable or transparent without starting over with a whole new piece. I think the plan was to make Scoop and Airborne with this head all along so it's not changing. This isn't the same thing as changing Salvo.
vintage Capt Grid Iron helmet and football grenades
vintage Backblast v1 missile launcher
That makes sense. Oh well! Worth a shot...Regardless of what comes our way, I'm excited to add scoop to my collection.
