If you don't have any background in shooting, processing and printing b&w film, it might seem reasonable to make such a claim. And I realize that, like 9/11 'truthers' and Obama 'birthers,' D&RGW 'Boilers' have a belief system, and that nothing I'm about to say will convince them.
But in reality, even if you know every detail from film type, filter used, to processing and printing details, any speculation you make about colors in a b&w image is just that - speculation. You can find many photos of locomotives where the boiler jack looks different than the cab and tender, because a different grade of paint is used on the jacket (Duco vs. enamel). And all the variables mentioned above react differently to that difference, as well.
Hopefully you'll be able to read this, if not notice the differences a filter makes in the image.
Notice that Jim details the film type, the filter on both the camera and the enlarger, and the paper. Why? Because it affects the final image.
This example is from Kodak's 'Darkroom Dataguide' and show how differently two different films can record the same scene:
This is why some of us simply don't buy the "you can tell what colors are recorded in a b&w image" - we know from our own experience how easy it is to manipulate how colors register in the final b&w image.
