🔎 Markings
• “Ed. Liesegang Düsseldorf”
This confirms it’s made by Eduard Liesegang, a notable German optics manufacturer based in Düsseldorf, active since the late 19th century.
• “Leuko Anastigmat”
• Leuko likely refers to a lens optimized for projection of black-and-white (leuko = white) images.
• Anastigmat means it’s corrected for astigmatism, suggesting good optical quality and flat field projection.
• “F = 30 cm”
This is a focal length of 300 mm — a very long focal length, typical for:
• Large-format projection lenses
• Possibly optical enlargers or scientific projection devices
Helicoid focusing mechanism (visible brass knob) — unusual for projection lenses, suggesting precise focusing was required. That points to use in a projection microscope or optical measuring device, rather than a simple slide projector.
• Large front element and robust build — typical of professional-grade equipment.

💡 Potential Uses Today
If you’re thinking of repurposing it:
• Photography (adaptation): Could be mounted to a bellows or large-format camera. The 300 mm focal length makes it suitable for portraits, landscape, or abstract macro if you’re building a custom setup.
• Projection: If you’re restoring or creating an analog projection system, this lens is ideal.
• Collection/display: This is a historically significant and beautifully built optical piece — definitely collectible.
