I picked up below lenses for a little pocket change - so little that I didn't put much thought into how to utilise them at the moment of purchase.
The seller didn't know anything other than he speculated that they likely was used for repro work, which sounds plausible.
Back at home; the internet was not as informative on the Schneider G-Claron lenses as I had expected.
It seems like Schneider-Kreuznach have deleted much of their legacy lens information from their website.
I wonder if anyone here can supplement with some knowledge on the following:
It doesn't say much on potential use, but as near field optimised, I thought this perhaps could be used as an 4X5 enlarger lens?
2. Left: Schneider-Kreuznach G-Claron 240/9, f/9-64. Front filter diameter 52mm. Serial number: 13 426 145.

The lens seems to be useable as a taking lens and possibly even allows mounting of a Copal #1 shutter. The lens in the link is said to be "glued" to an enlarger board. It is possible my lens is "glued" as well because when I apply medium force I cannot separate the front and rear.
I have never experienced "glued" in this manner before, though.
I imagine to use this as a taking lens on my 4X5 - I would be fine just mounting it to a lens board without shutter and use long "cap-exposures" with an ND filter if necessary.
I am guessing normal distance work will be OK even if the lens is optimised for near-field? (I don't do infinity landscape stuff).
Is there a way I could/should test if the distance between the front and rear parts of the lens are correctly spaced?
Visually it doesn't look to me like there is enough space for a Copal #1 shutter in the little space occupied by the enlarger board, so I am unsure what to make of that?
3. Center (more details in the photo below): Non branded single coated lens with font coated mirror behind the last element.
I have no idea what this could have been used for.
If I screw it apart, there is a front group that can be separated from the rear element. A flashlight seems to indicate 3-4 elements altogether - 2-3 in the front and 1 in the rear.
To my eyes it looks like half-a-lens which is terminated with the surface coated mirror,( which is held close to the rear element with a aluminium retaining ring).
The front group seems very carefully aligned from the rear lens element with several paper-thin metal spacers.
Any idea what this lens could have been used for, and if there could be any practical application for general photographic purposes?
Anything that can shed a little light on these is much appreciated - thanks
I'd love to put these nicely made objects to good use.
