Pullman green in 1906??? Very interesting. Here is a quote from the Superintendent of Motive Power and Car Department, 9-6-18:
We have in the past, painted our narrow gauge equipment a Tuscan red, but as economy will result from the use of the Pullman [Green] color, as we figure about 3 months longer service and $1.25 per car less cost for material, wish you would arrange hereafter as narrow gauge equipment passes through the shop to adopt the Pullman color as our standard.
From "Farewell to Cumbras"....CRA 1967.
So, when did Pullman adopt green? Were there any Pullman owned cars in operation over the D&RG in 1906? IIRC, the C&S used Pullman green on their passenger cars at that time...so it makes me inclined to believe that it was an established color.
Very interesting find...whether it is correct or an artistic license...
