Rare, Leaky Lens, Dallmeyer 38mm F4 C-mount Cine Lens

Rare Bleeding Lens Dallmeyer 38mm F4 C-mount Cine Lens

The nameplate is engraved with "DALLMEYER POPULAR TELEPHOTO F4 F=1 1/2"".
It appears to be quite old and uncoated.

Only one or two similar lenses appear in searches, so I believe it is quite rare.

The original mount is unknown as shown in the photo, but I have modified it to a c-mount in my workshop.
The material is brass, and it has been finished with black dye.

・The image circle is for Micro Four Thirds, and there is vignetting in the four corners.
・There is fine dust in the optical system. No major mold is visible.
　Please make your judgment based on the actual photos.
・Focus/aperture movement is smooth.
・The c-mount part is a new part created specifically for this lens.
　It has only been used for testing.
　The material is brass, and it has been finished with black dye.
・Accessories: Hood
・Some flange back adjustment is possible by the user.
・I have checked infinity focus and mounting with multiple adapters at the time of listing.
　Therefore, returns due to problems that seem to be caused by adapter compatibility will not be accepted.
　However, I will provide as much advice as possible if you let me know the symptoms.

*The attached images were taken with a Panasonic G-3.
*As a reference, I have attached a real-world photo of a radio tower about 300mm away from the shooting point.
　Please use it as a reference for infinity focus.
*You can search for "soba_tzuyu" on the web to see sample images.
