Below: A 1995 inquiry to the IRS about the taxpayer ID number used on Oswald's 1956 W-2 form from Pfisterer Dental Laboratory shows that the taxpayer ID for Pfisterer was created in January, 1964, not 1956 or earlier.

In January, 1964 the Warren Commission "investigation" was just beginning...how did that ID get on a 1956 W-2?
