Other version does not have the grid. Dragonfly - first version had a nose gun that pivots and swivels as shown on the box. This version might also have a slightly different coloured Wild Bill. There's still speculation as to whether this was due to fading from the sun. If anyone has this version that has a slightly different coloured Wild Bill, let us know so we can verify this.
Second version has nose gun that only swivels.
Night Raven - some had no landing gear notch and others did. Barracuda - some versions had a blue top half and black bottom half and others had a black top half and a blue bottom half. Unless more are out there, these are most likely oddball paint mixups.
