Not a Lieca lens for sure, and still a very decent performer for an old unknown slide projection zoom.
I put it on Sony Nex with a lens booster. No aperture control, so all shots are wide open, at f3.5. (I first noted the lens did not have the aperture indication. I was wrong then, it is clearly written on the barrel, I confused it with another slide zoom). The bokeh is not the mildest, but nicely uniform. At times it makes me remember a 100mm projector triplet by Angenieux.
Put on a lens booster the lens vignettes quite a bit, and this makes part of its character. Autocontrast applied improves slightly blowed SOOC jpegs (produced by the lens without hood). BW simple conversion seems to work perfectly well.

Looks nice. The lens must be pretty rare, can't find anything about it. Then again I never get any french results in Google.

Fellows, thank you for you feedback!
Here are the shots of the lens. I am not sure it is French. It could also be a German one. There is no precision on the barrel. I tried to remember the circumstances in which I got it (was it attached to a projector or alone, was it from a French or a German seller, etc.) and found no trace, which is unusual. So, for the moment it remains a riddle.

Some more samples.
#1 This one shows how the lens renders detail in close field
#2 This one and the next is a simple BW conversion with minor exposure corrections

Strangely missing a hood

In my experience I have never met a slide projection lens with a dedicated hood. Or you mean a protrudent part of the barrel itself? |

Yes, they almost always have a receded element/fixed hood.

Maybe it had a clamping hood, so you could change it with focal length.

Interesting idea. If we knew the projector it was attached to, this could be a hint. |

I found the trace of my exchange with the lens seller. He was French, regularly selling second hand photo equipment, and he acknowledged to never heard about this lens before, neither of its origin. So not much to add, just the lens' latest location in France.
