Swedish ABB bricks

In 1950 Geas got a license from LEGO to make Automatic Binding Bricks, using their moulds and tools to make the bricks and boxes. So except for the colours and plastic material these bricks are identical to LEGO ABB bricks in shape and form. When the contract between Geas and LEGO ended, Geas started making their own bricks and boxes known as PRIMA. The ABB bricks were made using two different plastics as seen on the picture below. A shiny slightly translucent plastic, and the more well known CA (Cellulose Acetate) plastic on the bottom row:
