This is kind of a cross-over post from the marketplace, but I thought that it fit better down here. I have a friend with lots of Kodak Carousel 140 slide trays. As many as you need for $7.00 each. Capacity: 140 slides, boxes and trays are in like-new condition and gently used, for use with all Carousel and Ektagraphic slide projectors except models 550, 550R, 570, AV 580, RA-950 and Ektagraphic RA-960 and S-AV models, shipping at exact cost. E-mail me for details.
