Totally forgot to come back here to let you know what I found out .

That kit is most likely from 1971 as I found a "date: 56717 model: 950 bw" label inside the bass drum.

As expected when I got it, I cannot afford keeping it and put it on sale...

Probably too expensive for you guys in the US but not necessarily if you're in Europe.

Please PM me if you have any interest.
