Well, while I can't tell you why this block appearantly got beat by the "Murks3 rev1.1", I'll provide a link to the "orignal" discussion in a german forum:
http://www.kaltmacher.de/viewtopic/t-23050.html
Of course, you'll also find some more pics there aswell.

Actually, this block only shares some similarities with the "Murks3". It's a different design - this block has 36 jets/cups vs. the "unknown number" of the Murks3 REV1.1 (couldn't find this info anywhere) and the Murks3 with 25 jets/cups.
