Toys that have a Secret Projects aspect

[uk 75]

Back in the 80s I purchased some toy plastic block sets made by a Spanish firm called TENTE.

I used it to make rough models of CVA01 and Typhon cruisers. I still have the sets stashed away.

TENTE went on to make special sets which allowed you to build real ships like the Franch carrier De Gaulle.

The CPU block, the camera block.

The antenna block really hurts when you step on it.
