Here's my OK Engines Seaboard Air Line sleeper Pinehurst:
Lightweight, Budd (5-1-4-4) 5 Double Bedrooms,
1 Compartment, 4 Sections, 4 Roomettes
Budd Lot # 9658-168 Plan 9537
The trucks are from GGD, the ends, floor, and doors are scratchbuilt, and the diaphragms are from PSC.
The aluminum body is very nice IMO. Like Mikeg said, OK Engines will put windows wherever you specify or follow the Budd plans he has.
If I was to get another I would buy only the aluminum body and window plastic. I didn't especially like the ends that were provided, however the owner (Ted Brebeck) stated they were looking into making new ends with better detail last time I corresponded with him. The GGD trucks are top notch, interiors can be gotten from PSC and Keil Line.
OH! Forgot to mention mine are 3-rail, but only the trucks would need to be changed from 3-rail to 2-rail.
