The one the OP needs is this one:
There are several other german ones, including ones with a slight resemblance like
LKM and
CS, but at anything but a short glance the differences would be clear.
Tricky is a model of
MF slide tray which looks so similar that one seeing it on a photo on its own most likely would consider same with just cosmetic differences.
And indeed, the OP hinted at the MF version at the link he gave!
But the Ikolux AJ24 is a 35mm projector!
As a reference has been made to the P11 projector, which takes both trays, here a rare photo showing both.
The 35mm one is the sample next to the projector!
