Vintage Starrett No. 555 Set of Six Instrument and Jewelers Screw Drivers

This item is a vintage set of six Starrett instrument and jewelers screwdrivers, model No. 555, presented in their original red cardboard box. The screwdrivers feature metal construction, likely steel, with knurled handles for improved grip and control during precision work. Each screwdriver appears to have a flathead blade of varying widths, with the box indicating approximate widths ranging from AA-.025" to E-.100" (and C-.070", D-.080" also listed). The blades appear to be in good condition, showing minimal signs of bending or heavy wear, suggesting they have been relatively well-preserved or lightly used. The overall finish of the metal on the screwdrivers appears consistent, with a uniform, slightly aged patina that suggests its vintage nature. No significant rust or pitting is immediately visible on the metal parts. The box itself is a prominent feature, indicating the manufacturer as 'Starrett Company, Massachusetts, U.S.A.', and clearly displaying 'TRADE MARK REC. U.S. PAT. OFF.'. The red cardboard box shows visible signs of age and wear, including some creasing, scuffing, and minor tears, particularly along the edges and corners, as is common for vintage packaging. Despite the wear, the text and Starrett logo on the box remain largely legible. Inside the box, the screwdrivers are nestled in what appears to be their original fitted slots, likely made of cardboard or a similar material, which has also aged and shows some discoloration. This set appears to be from the mid-20th century, given the Starrett branding and general style of packaging and tools. The quality of Starrett tools is generally high, indicating good craftsmanship and durability for their intended precision tasks.
