Help me identify this lens.

I received it in a batch of darkroom stuff. It says Astragon 1:4.5 f=180mm. It is mounted on a lens board measuring 5" by about 6 3/4". I have no use for such a lens and have researched it with plans to sell it, looks like it may have been made by Fuji, though I am not sure.

Pictures are attached.. anyone have an idea.. or better yet.. anyone want to buy it?

Thanks.

Well, you already know it's an Astragon. You know the focal length. What else do you need to know? It is a Japanese lens. There is some noise floating out there that says it was made by a smallish lens manufacturer in Japan. They do not have a particular reputation that I've found. I have one, a Commercial Astragon 210mm in a Copal #1 shutter. I got it with a LF camera. I have not used it yet, so can't comment on the quality of even one of them.

Made by Yamasaki, I think. They also make the Congo line.
