This listing is for a sealed, new old stock Agfa IT8 Color Reference Kit.  This probably came with an Agfa Horizon Scanner. 

The Horizon was an awesome scanner.  It could scan up to an A3 (11 3/4” x 16 1/2”) in size and weighed a hefty 141 pounds.  The IT8 Kit is still factory sealed and has been kept in a cabinet for many years.
