Very rare and hard to find. Ford designed their own microfiche (of course they did!) with a much higher ratio (4X more than standard microfiche) so they could cram more parts info on each sheet. Comes with 6 parts catalogue films for various years/parts. More can be found/purchased online. Also comes with a spare bulb - try finding one of those. Collection of automotive themed stickers and collectible antique GST sticker thrown in for free ! Works fine, I just need the space for other stuff.
