What slide trays are compatible with a leica ca2500

I managed to "win" one of these and can't find any manual or a specific reference of which slide trays will work on this projector. I know that there are 30 or 50 slide trays that leitz makes that should work. Would any carousel trays from other manufacturers work? Thanks Norm

Traditional Leitz trays are straight and viewed from the rear fit on the right side of the projector.
The series that uses circular trays are standard Kodak style Carousels.

Thanks , I will get one of the straight leitz trays and when I get the ca2500 I will see if it takes an old kokak tray. Norm
