Instead of words of wisdom just enjoy this video.
This is a great video showing the first assembly lines at the original Ford auto plant. Neat to see those guys making the old wooden wheels, by hand mostly.. The places that car could go...is amazing!"
The great depression killed the model T. There was a Ford plant by the Passaic River off the "plank road" Comunipaw Ave,which in the 30s was cobble stone. Before the Holland Tunnel and the Skyway were built this was the route to the ferry.
I can remember seeing 100s of new Model Ts stored there waiting to be delivered to dealers who could not sell them.
