I enjoy old lenses.
The early 2.0 version of the XR RIKENON is popular, nicknamed the "Japanese Summicron."
This lens is the 1.4 version, which is superior to the 2.0, and is less common. It's a large lens and feels substantial.
It has the same construction as the early models, so it's likely made by Tomioka.

This particular lens has few scuffs or paint peeling, and both the aperture and helicoid function without problems.
The optics have some slight discoloration on the rear lens, but I didn't notice any impact on the image quality within the range I photographed.

Sample landscape images were taken with a SONY α7Ⅱ + adapter + this lens.

I am selling it because I have limited storage space.

I hope someone will use it.
