STORY GOES 1937 Cad & LaSalle were the first to see Phillips. Do not believe PACKARD saw them until later. Believe one of the Parts Books thinking early 40s has a fastener listing which show Phillips & Numbers. With the part number you could trace it back thru a late 30s Parts Book to find out there first use.
