What ever happened to?

I’ve been buying old copies of aviation magazines and in one there is an article by Roy Braybrook about Air Force trainers around the world.

There is also a small chart with some trainers on it where to have to guess which trainer it is, I knew all of them except one, the last one. The SAAB SK-2

So what happened to this trainer? I’ve never heard of this trainer, can someone show me some details and pics of it please?
