Early version Famo/Bilstien crane

[nsmekanik]

I've started puting together Trumpeters 1/72 kit with Bilstien crane early version. Looking at the few pictures I could find, and the parts layout, I'm assuming that this is the early mounting of the crane, on the early version of the Famo, with full crew compartment, and the later mountings did away with the second row of seats, and has nothing to do with the version of famo.

All the pics I can find show only the front row of seats, would anyone possibly have any info/pics of this earlier version with full crew compartment?
