Looks like you should have bought this one too.
I all ready have one.
The story goes like this.
The top had a keyway formed into it that would line it up with a slot that was in the lighthouse. This was so the top would be placed in the proper position.
To speed things up one or more of the employees filed down the keyway. Probably everything was going smoothly until the employees were called away or replaced. The person or persons who took over had no idea of how it was to line up and there was no keyway to guide them.
At the time it was not very difficult to find one with a rotated top. I was able to locate three at dealers in Florida and Paul Bradey was also able to locate three at dealers.
But there was more to it then being rotated. Because of the position of the door on the top piece there was a possibility of a total of 6 variations. I believe all six positions were never found and as Rich said most of them rotated the same way.
Jim Rutherford announced in his news letter at the time that there could be as many of 400 of these variations.
