I’m in the process of removing all the cast-on detail from two HO scale Roundhouse 50’ single-sheathed automobile cars that will become Western Pacific 40001-40100 (originally 13001-13100) series cars.  Separately-applied details will replace the cast-on details.  I’d like to repaint these cars in a proper “boxcar red” color that would be appropriate for the 1947-1950 time frame.  

I’d be grateful for advice on what paint/color would be a good “BCR” match for these two cars.

Thanks
Pete
