Thanks Erik!
That's a Beautiful Shot of #3700 with the Green Boiler! So, as you have mentioned above. different engines retained their green boilers longer than others, such as the case of #3700 here which apparently has retained the green into at least the late 1940s... Very cool, and Interesting...
Erik... Do you happen to know which of the 3700 class retained the green boilers late into their lives, such as #3700 here?
Here is D&RGW Class L-105 Standard Gauge Steam 4-6-6-4 #3710 rolling past prison south of Buena Vista. Colorado...
Note the color differentiation of the boiler vs the cab, and the sand and steam domes... Looks like a Green boiler...
Overfire jets have been added, so this is post 1947...
This last photo of 3710 is the most compelling piece of evidence I’ve seen to date. I respect what Scott is saying about it but the contrast between the sand domes and the boiler strongly suggest “Green” to me. David, may I ask where you found this photo?

Hi Chris,
I feel the same as you. Respectfully... When I see that photo, and you look at the Pilot Black, the Cab , Sand domes, even the coal in the tender, it looks black as BLACK...
Then when you look at the boiler, it looks very much a greenish, lighter color... Lots of contrast with the greenish looking boiler... Also, note the overfire jets present, indicating post 1948...
Would you believe I found this photo on Pinterest? Type in : Rio Grande 3710
