Kodak Ektagraphic III AT Slide Projector

This is a Kodak Ektagraphic III AT slide projector, a professional-grade optical device widely utilized for slideshow presentations during the late 20th century. The unit is housed in a heavy-duty, aluminum-reinforced flight case with high-density foam inserts, suggesting a history of industrial or professional use. The projector features a light-grey high-impact plastic body with a circular mount designed for carousal slide trays. Notable controls include a 'Select' button, vertical adjustment switches, a timer dial for automated slide intervals, and a main power switch. On the side, the 'Ektagraphic III AT' branding is clearly visible in yellow and white text. The projector is equipped with a black focusing lens and includes a wired remote control stored in a dedicated foam cutout. The overall condition appears used but well-maintained, with minor surface scuffs on the plastic housing and dust typical for vintage electronics. The metal-trimmed carriage suggests this kit was designed for frequent transport and protection against mechanical shock. Manufacturing originated in the USA by the Eastman Kodak Company, likely dating to the late 1980s or early 1990s.

Upon my virtual examination of this Kodak Ektagraphic III AT, I find the unit to be a well-preserved example of high-end analog projection technology. The 'AT' designation indicates an 'Auto-Timer' and 'Auto-Focus' model, which represented the pinnacle of the III-series. The presence of the aluminum-reinforced flight case and custom foam inserts significantly enhances the value, as these accessories suggest professional archival or institutional ownership rather than consumer use. The body shows typical minor scuffing, but the integrity of the lens housing and remote appears sound. The market for these units has seen a resurgence among multi-media artists and analog enthusiasts. While basic Ektagraphic models sell for under $100, the III AT variant in a professional road case commands a premium. Recent comparables for serviced units in similar protective casing range from $250 to $400. However, this value is contingent on mechanical functionality. This photo-based appraisal cannot verify the condition of the internal gears, the integrity of the drive belt, or the remaining life of the lamp. A critical limitation is the inability to test the autofocus mechanism and the timer accuracy without a physical carousel and slides. For full authentication and valuation at the higher end of the range, an in-person diagnostic to ensure the solenoid-driven advance mechanism is not 'sticky' and a verification of the lens's optical clarity (absence of fungus or delamination) would be required. Provenance documentation showing its maintenance history would further solidify this valuation.
