Thanks for the answers.
You're quite right about them being hard, especially a little bit of center it feels like hitting into a rock. Not a pleasant feeling through the spine, one could think I would learn not to hit like that... The shaft is Multistep R. Grips are overall ok, a bit dry on two or three clubs. The grips are also asymmetrical, it's like a ridge on the back side.
The thing I find frustrating is that it seems to be impossible to find any information on the Tornament-line, might it be because it was a one time thing? One thing that i didn't think of before is that there are a driver and a metalwood in the set, also marked Tournament. My understanding is that thees wasn't available until the mid 80's? The design is otherwise like persimon, down to fake screws around the sweet spot for no apparent reason.
