RETURN!

Look at the shape of the cemented group behind the aperture, and notice why:

There is a chance not far from 0% of doing it properly. This thing most likely was polished AFTER cementing the two faces, not afterwards. That's my guess knowing very little about optics but a lot about "educated guessing".

You should only keep a thing like if you have a donor lens, and paying very little as a For Parts lens.
