If you are interested I have several trays for sale (cheap) for this projector. I had one that I picked up at a pawn shop for very little money. I was great for the 30 minutes that it worked, the transformer blew, the repairman said the parts were quite expensive, so I chucked it. I kept the lens and use it as a loupe. PM me if your are interested in the trays. The light quality and image sharpness from a Leitz projector is far superior to any other brand, good luck with yours.
