What set(s) are these 2x2 hexagon bricks from? I've inherited quite a few interesting pieces from relatives who outgrew LEGO. Any idea what set(s) these came in? They don't have any numbers so I can't look them up on pick-a-brick or anything.
You have the following pieces:


6037 - Brick, Modified Octagonal 2 x 2 x 3 1/3





6043 - Brick, Modified Octagonal 2 x 2 x 3 1/3 Corner





6042 - Brick, Modified Octagonal 2 x 2 x 3 1/3 with Side Studs





6032 - Brick, Modified Octagonal 2 x 3 x 1 2/3 Sloped




These were used in about 10-15 sets during a brief period from 1995-1998, most of them in the Aquazone theme, but some made their way into other themes as well (e.g. Castle).
