Actually, Michael, the CRRM doesn't "have" a K-37. the Colorado Historical Society owns #491, it is on a "long term" display agreement. I don't know if they would want another "project" on the property, but you never know....
By the way, as one of the handful of volunteers from the Boulder Model RR Club who painted #491 over 20 years ago from the rusted hulk she was when she was delivered from Alamosa, I appreciate the work that goes into these things, even on display.
My hat is off to those who have undertaken the effort to paint and preserve the equipment in Silverton. It is thankless and taken for granted by others, but what they are doing does matter.
