Bruce Johnson might have a picture of one.  Here's what he wrote on his website:

"After a peaceful snack, I began to work my way back toward the PCT, but I had not gone 100 yards before I glimpsed an unnaturally white shape on a distant tree trunk. Enameled metal, with the original tasteful logo of the Oregon Skyline Trail, and not shot full of bullet holes, it was a treasure indeed. 50 years back into History my mind leapt….the 1930's, so long gone, the trail builders rerouting the original Skyline Trail from the lowlands route of the early 20's, high up to the spine of the Cascade Crest. It was probably the CCC men, grubbing and marking this trail lovingly. How many years had gone by since their work was bypassed by the modern PCT? And how many quiet years had it been since human footsteps had trod this trail? And how many more years would this unmaintained and forgotten gem exist before Time took it back, and it became so dim that it would be lost to history, forever?"

Let us know what you discover.

Seems like I may have seen one in California on the John Muir Trail.

The ones we are looking for Say OREGON Skyline Trail, not in California

Here's a link to September 23, 1937 newspaper article about signage on the Skyline/PCT:
