OK, and FWIW, having taken apart this car here's where this project has got to. It's near complete, but I have to re-assemble the car, which for me is always the most nerve-racking stage of any project.
My intention was to produce as near as possible a prototypical SP dome car interior, to go with Scott Mann's beautiful GGD car. Bear in mind that I am really a trespasser on this 3rail SCALE forum as I am a dedicated traditional O gauge modeller. Maybe unfortunately, that governed how the project progressed.
I posted above what the stock interior looked like when I extracted it from the body shell. Using some historical SP concept drawings and the few color photos of these cars that exist, I decided on a color scheme - even including a "carpet" (which is inkjet printed fabric). This is how the dome seating area assembly turned out after laboriously removing and re-installing all of the separately applied details, including the fine 3D printed "Smokadors" that came stock, which I "chromed" using a special ink product. The curved seating areas in both parts of the car also have an imitation fabric covering:
I did this notwithstanding that a fellow who actually owned the first car in this series, SP #3600, told me that the decor was really fairly plain and was assembled out of very conventional building products of the time. Anyway, the signature features of this series of cars, at least based on my research, are the cathedral ceiling lounge area and the native northwest leaf screen that separated it from the dome seating. Again, I wanted a prototypical model of this area in particular but the small scale and my available material that I can actually work with (mainly plastic - I have no metalworking or 3D printing skills) limited what I could do. So, like most O scale passenger cars, this is really only a representation of the real thing:
I like eye candy in terms of small details, and basically what you can get any more in terms of proportionate O scale figures is limited, so the lounge seating area has come out slightly whimsical, using two scales of figurines and some that are, uh, unorthodox. I mean in particular the contemporary Chinese girl taking a selfie and the conductor, whose gold watch that I fabricated from plastic tubing and a pinhead actually looks as big as a ship's compass (which might conceivably have been useful back in the day when these cars ran):
This is not quite finished as I have some other things to glue in place, and then some effort to get it all re-attached to the body shell. There is also a separate lighting circuit (for some Pullman table lamps just visible in one photo) to accommodate. But at the risk of offending purists, here it is.
