I put a post out a month ago about my BF. Mine has very strange stuff also:
1) right slingshot is different then all others, it has batman arm on it
2) upper plastic around the right vuk is white/gray in color and has a checkerboard design on it. only place I ever seen one is on the flyer.
3) target back in the middle has a white plastic not purple. also only seen on flyer.
4)in front of the vuk there is a red insert that says Mr E, mine is a white insert that says Mr E. also white on flyer.
I have done tons of looking around for anything like what I have and can't come up with nothing. the plastics are not replacements or hand made for sure. I too have a translite with no white backing . I have looked on the serial database and mine would be the second lowest number on there. someone has got to have some idea of what gives.
