Re: Is this WWII era spur narrow gauge?

In the second image of the first post, there are road railing posts, I'm surprised no one has taken up that reference. So, I did...

When asserting measurements with in-photo references you have to take care with the selection, as both the reference and the measured object need to be about the same distance from the camera. So, I took the second post back, or, third from the left, and measured its width of the widest presented side. It's a bit canted from flat-on the camera plane, so this will be approximate. I tried a number of dimensions, and about 8" (~20cm) correlates with about standard gauge of the rails at the same distance from the camera.
