I am fairly certain that Westerfield offers the post-war 7/8 GN USRA clone.
I was one of the lucky ones with Andy Carlson's castings. I have his 50-foot steel rebuild using the old Walther's 50-ft SS underframe with fishbelly cnetersill. Mine is Orange & Green with DF and delineators. I also have two models since offered by Sunshine, the Pratt trussed SS 40-foot boxcar that built into a very nice model and one the GN's Plywood cars. This required Detail Associates 4/5 Dreadnaught ends and Red Caboose roof. Mine has orange sides and black ends and roof.
