Cascade trestle/mile sign

The Friends' MOW milepost and whistle post team is researching what signs were placed on the railroad's major trestles, and we wonder whether anybody has any older photos showing a mile sign or any other signs on Cascade Trestle, which is at Milepost 320.
A frame from film shot in 1978 by one of our team members is below. It's marked where we think there may have been a metal mile sign -- about the size of an automobile license plate -- attached to a horizontal timber at what would be at roughly the level of ties on roadbed. To see the marked piece of timber, you may have to move the vertical slider to view the bottom of the frame.
The view in the frame of film is from the west end of Cascade Trestle, looking east, toward Osier. There also may have been a mile sign on the east end of Cascade Trestle. It's our understanding that major work replacing timber on the trestle was done after the film was shot in 1978.
From what we've seen on a photo of a Lobato Trestle mile photo taken before the fire, any older mile signs on trestles were likely to be extremely faded and very hard to read. FYI, the sign on Lobato Trestle was mounted on a horizontal wooden wing off the guard rail, at about waist height.
If you have or know of images showing signs on the larger C&T trestles (Cascade, Lobato, Los Pinos, Chama River), please either post a reply here or contact me by email at pauldavenport@cox.net. Thank you.
