Describe Oliver Manufacturing Company here ... again, checking on location before getting invested in creating entry.  Found an Oakland Tribune article from June 17, 1917 about the Oliver Manufacturing Co. entitled "Making Engines for War" but cannot read as the print is too blurry and small.  For those with better vision, does it list the address and/or location of the plant?

If you download the PDF, it's easier to read -- the article says the new plant will "cover the entire block
bounded by Fourth and Fifth, Jackson and Madison streets."
