Aside from those in the Alamosa yard, Punk Blackstone told me he liberated all the remaining ones on the Alamosa to Durango segment in the late 60s when everyone knew the last runs were being made. I saw some of them in the basement of the Blackstone Apartments in Durango where he lived, and supposedly he sold everything to a collector. He also acquired a number of the remaining phone sets, and boxes of paper work out of the Silverton depot attic. He missed a bunch of Pullman Palace envelopes that were tucked into the ceiling joists that I later found.
