So I am back from vacation and continue to build.
In one of the space model groups in FB, I came across the assembly and refinement of Ken's model from Luk Rombauts. He kindly shared his improvements and developments.
True, he has no instructions, he has to collect from photographs.
I completely abandoned the seats provided by Ken, since they are not at all similar to what was in the command module. Luk has made the seats as faithful as possible, but they are significantly more difficult to assemble and have amazing detail. At the moment, very little has been built, but it already looks like a seat.
