Weaver also did the streamlined B&O Cincinnatian.
Sunset 3rd Rail had short run for B&O P-7e 5315, which had a smooth faced pilot and running board side skirting. But I guess that's more semi-streamlining than a full measure job.
Sunset 3rd Rail also had planned to do the B&O's first Otto Kuhler streamlined bullet nosed, Royal Blue 4-6-2 and a set of cars for it but dropped the project for lack of interest.
