Vintage Bell & Howell Slide Projector Model 975Q Powers Up But Selling For Parts

Description

You are bidding on a vintage Bell & Howell Slide Cube Projector, Model 975Q.
When I plug this in it does power up and the lamp lights up however, I can't get the photo slides to move through the projector. I don't have a manual with this so I'm not sure how exactly this is supposed to work. So, because of the slides not moving through the machine I am selling this as non-working.
Please look at all the photos for reference.
