Destroy Death Star Game

I got the Destroy Death Star Game way back in 1977. I remember playing the game a few times and enjoying it every time. The game has a board with a rotating Death Star, and four game pieces that holds three X-Wing fighters each. The object of the game is to move around the game board to the Death Star and then make the shot to blow it up.  I lost the directions for the game so I am basically describing it on memory. It's a cool looking game and a lot of fun.
