Come to think of it, the line north of Alamosa used 126.3s. I have one that was found by a rancher near Moffat.
The colored HG beehives came off standard gauge routes. Almost all pastel colors. Clears, off clears, steel and sky blues. I think some mint greens, light purples maybe. I want to say there was an occasional strong color. If you know any of the EIC crowd, the gentleman who coined the term "glower" with respect to HG Petticoat beehives is the subject matter expert.
Good call on the CD 144s. To further flesh out the D&RGW glass, hemi blue CD 214s, and dark green Hemingray 152s were used over Tennessee Pass. The old narrow gauge over the pass used 126s...and for some reason I want to say 1872 Patent glass as well. But I think I might be wrong about that, probably confusing with the South Park glass.
