I'm not that old, but I did work on similar assy. lines to get some college money in my whipper snapper youth!  All pre OSHA of course.

This video is just under 10 minutes long.  Some of you may not want to sit through it.  Others, like me, will find it instructive and mesmerizing:

"A 1936 Chevrolet assembly factory. Note the automation that was already in
place, the workers lack of any and all modern safety equipment, glasses and
helmets, and they ALL know exactly what to do and it's getting done. Note also
that when the body comes together with the chassis that it is in FULL trim,
Interior, windshield, all glass etc. is already in place as it is dropped onto
the awaiting rolling chassis, "AMAZING". Simplicity at its best. Note that while
the metal finishers are checking the sheet metal for minute and tiny flaws and
defects that they are wearing heavy leather work gloves. How would YOU like that
repetitious job of placing 3 rivets in the 3 holes on the chassis for about 35
to 40 years."

Amazing new Info on this film..!
FYI: A Trip Down Market Street was filmed in 1906!! 4 Days Before The Quake.

Dir...Miles Brothers.

This film, was originally thought to be from 1905 until David Kiehn with the Niles Essanay Silent Film Museum figured out exactly when it was shot. From New York trade papers announcing the film showing, to the wet streets from recent heavy rainfall & shadows indicating time of year & actual weather and conditions on historical record, even when the cars were registered (he knows who owned them and when the plates were issued).. It was filmed only four days before the quake and shipped by train to NY for processing. Amazing but true!

A trip down Market Street. The original version of which can be downloaded at....www.archive.org...suffered badly from "Film Roll" at the beginning and end, this version however has had those faults corrected and shows alot more detail particularly at the end were the film froze and skipped frames.
