That's fine work. The historical research on these cars is always rewarding. Lining the seating up to match the car windows is always a complicated job. More than once I have had to start over again.
I've posted elsewhere a photo essay on my latest dome project (in the Lionel 21" Excursion dome observation car) but I went a little overboard on the partying passengers. However like you in the dome I reconfigured the seating to match photos of the prototype (still in service in the UP Heritage Fleet) although I decided it would be far too complicated to try and match the upholstery:
(P.S. for some reason this first photo does not insert correctly in the post but it is attached below.)
BTW, I've figured out that the Swiss cheese effect is because K-Line used a limited number of passenger car floors and they came pre-drilled to accommodate just about any passenger car interior seating/detail configuration. Of course in those days the details were hand-applied.
