The Budd 10-6 sleeper in this GGD set is fluted. Pullman also made a fluted 10-6 sleeper, but the fluting was not the same.
Budd:
PULLMAN:
The fluting above the windows on the Pullman car matches the fluting below the windows, whereas the fluting on the Budd car is smaller. Both cars have the smaller fluting on the roof, just can't see it in the above photos.
Then you have the smooth side cars. I haven't looked to see if ACF made any 10-6 cars, but I wouldn't mind seeing some ACF cars.
I'd like to see GGD offer individual cars and all the different railroads that owned them. I do believe he'd get more orders if we could but the exact car in the railroad we wanted without having to buy a 6-car set.
I've tried to make the PORTSMOUTH car, but nothing I can do will come close to what GGD has done with this new 6-car set.
