I thought occasionally I've heard of the later blue one with no windows.
Maybe sort of rare, but I'd bet other examples of the earlier green one with no windows exist.
Edit: I think I may have figure out why some have no windows.
I checked mine, and there are no rivets to hold the windows in place, so some may have fallen out durring the assembly process.
I think my brother's #12 blue Land Rover has no windows.
I'd like to hear from SMS88 or someone who knows much more than I do.
By the way, I think the green color one is far less common. Seems like I'm allways tripping over the blue ones.
I have about 6 and had more. They must have made millions of 'm!
I'd love to find a nice dark green one, that's a great color.
Have a couple gold Superfasts, those look neat too.
