Leitz Wetzlar Parvo 250 Slide Projector - Your opinion?

I have the chance to pick up a Leitz Wetzlar Parvo 250 slide projector in very good condition.

Does anyone have one and, if you do, what do you think of it?

The Parvo is the mechanically a bit more simple predecessor to the Prado range that became the standard slide projector in the 50s and 60s (and beyond that) in westgerman education and institutions.
Your sample even already is a Prado version. And it includes a filmstrip device, something I never came across.)

As with all projectors the essential issues are condensors (eveness of illumination) and the lenses (image quality).

I assume you already have got a tray projector with high-end lens. In this case a simple slide-stage does not make sense, aside of the basic approach.

Thank you. I was thinking much the same in regard to its usefulness. I’ll let someone else purchase it for their enjoyment.

Too many toys...

I have one that I bought a couple of months ago, but haven't had a chance to use it, as it needs re-wiring. But the simplicity appeals to me. I have lots of slides, but I don't want to accumulate or source a bunch of trays for a more modern projector.
My other slide projector is a similar design Kodak, but it's much larger, so the compactness of the Leica appeals also, and I plan to sell (or more likely give away) the Kodak.

I have accumulated several Leitz projectors over the years. A friend recently borrowed my Prado Universal ( the simplest basic small projector designed for traveling salesmen), and was astounded by the high quality of projection. The Prado shown by OP is very handy if need to look at only a few slides. Pradovit 250 is great...when it works. But parts are no longer available. I have a Prado 500, like the Prado, all manual, as well as the Linhof version made by Leica to take 6x7 slides. All are excellent projectors.
