Kodak slide carousel trays (Greektown)

For carousel slide projector. The trays are used but emptied. Update on quantity = I have emptied 7 trays with 80 slots each (from 1960s) + 2 trays with 140 slots (1970s or 1980s). All Kodak brand. I would love to give away any quantity instead of dumping them.
