Two Vintage Retro Slide Projectors Leitz Wetzlar Rank Aldis

Two Vintage Retro Slide Projectors Leitz Wetzlar Rank Aldis
These came in a job lot and all I will say is electrical equipment is not my area of expertise.
I can say is I've plugged them in, a light comes on and there is a fan sound. This of course does not mean they are in full working order and I am not selling it as in working order.
Either you can get this going again, of course you may just want it as a beautiful piece of old mechanical engineering displayed on a shelf somewhere.
These are both sold as incomplete and in all honesty I wouldn't know what complete is so please take a good look at the images yourself to see if these are any good for you.
