This is a vintage GAF 2800 Sound Super 8mm film projector from the 1970s, made by General Aniline & Film (GAF) – often a rebadged version of an Eumig model (like the Eumig 820 or similar). It's designed for projecting Super 8 sound films (magnetic soundtrack playback), with features like: Zoom lens (typically f/1.6, 17-30mm). Automatic film threading. Forward/reverse projection. Variable speeds (18/24 fps). Built-in speaker with volume/treble controls. 100W halogen lamp. Reel capacity up to 180m (about 600ft). It's a solid mid-range sound projector from the home movie era – great for playing old family Super 8 films with audio.
