Hi,
On the subject of diagnosing the color, I humbly submit that this is more than likely a color of calf scours which we can type here with all confidence of not being censored.
Obviously the railroad had been involved rather intimately with the movement of cattle, and some may have found some of the colors produced as a result of transport somehow inspiring, arriving at the color we are attempting to identify.
Certainly some "chips" should be easily obtainable for comparison!!!
Cheers,
Stan
