I solved my mystery by myself. I found what I was looking for. It is called the Diesel Iakop 827N :)
Looks pretty good.
Here's the link, might be helpful to those ones who like this wash, like me: http://store.diesel.com/cz/regular-slim-tapered_cod42338576wq.html
p.s. I see that Diesel is currently updating their Online Store with more and more new washes and cuts from the Spring/Summer 2014. They are constantly putting new stuff in.
I see that they have put the Blue Eyecon Thavars and Belthers, they have the Sleenker 824Z as well and many other new washes and cuts. That's nice. Finally, it was about time :)
