Hope this won't be considered off-topic.
I am looking for some old TYCO brand Lego compatible sets. They were available around 1988.
The first is a Castle kit (NO. 5280), the second is a Space kit (NO. unknown). Both of the kits contain special bricks. Hard to describe but here goes.
The first piece is a triangle with one large bump on top. Each side is the length of a 1x2.
The second piece is the first one with a 1x2 on each of two sides. Six of these fit together to form a twelve sided cylinder. Great for Castle towers.
The third piece is the basic triangle with a 1x2 on one side and no bump on the triangle part.
There may be other kits that contain these same angled pieces. Any info on such pieces would be appreciated.
