Paul,
The Patriot truck manufacturing company in Lincoln, NE, did some truck work for Chevrolet in the late 20s.
They at first did whole trucks and then went on to making cabs and stake beds.
I have seen stakes beds with a decal or plate with the information. They say the company is from Havlock, NE, which is downtown Lincoln.
My 30 LR was manufactured in Kansas and has been local for pretty much most of its 80 years.
Bring your truck down to Camp Creek in Waverly next summer!
I'll be running mine there!
Hope this helps.
