This is a new old stock pair of Trico brand wiper blade assemblies that are part number PR-16.  So many  of these have been replaced with modern plastic blades that are not even close to what was original in the 50's to 60's.  These have the bumps in the rubber which are hard to find.  These are the shiny polished stainless steel type finish mainly used before 1967 but will fit later cars with the wide bayonet type arm with adapter or dead locker type arm.  Trico is embossed into the metal blade holder at both ends.  These fit the following according to my Trico catalog as a replacement red letter blade; Pontiac Bonneville 1959 with overlap blades; Lincoln 1959; Mercury 1959 with vacuum wipers;  1961-1962 Thunderbird; 1961-1964 Econoline; 1963-64 Fairlane with 2 speed wiper; 1963 Meteor with 2 speed wiper.  These are in excellent show quality condition as are the original boxes. You must ask for the adaptors if you want them included in the package as these are not included in the box.
