I have been surprised to see that the West Coast early Ford Branch buildings are still standing. Among these are Seattle, Portland, Los Angeles. I can't remember if San Fransisco is still there before Ford moved to Richmond.
Here is the 1923 Photo of the Los Angeles Branch and what it looked like in 2011. It is still at 2060 East 7th St .
Did they cover the windows on the first two floors to keep the neighbors out of the building?
Lots of them still exist. The one in Dallas was converted to loft apartments.

The one in Cincinnati is office space.

I'll have to drive down 2nd some day. The cross street is probably Main. They tore down the Terminal Island plant about 20 years ago, but I don't think they ever made T's there.
The exterior of the Seattle plant is still relatively intact; see https://digital.lib.washington.edu/architect/structures/4902/ Click on the image shown to enlarge it.
The exterior of the Portland, Oregon plant is also intact: see http://tagwh.at/t/1982
