Hi everyone - first off, thanks to anyone who can help.

I have an Ultron 28mm 1.9 that worked flawlessly - until I dropped my M8 from about a 4-foot height.
The lens took the brunt of the fall - and as I looked in, I saw that one of the blades had come loose and was bent.

A few minutes later, I have the entire lens disassembled (which I have done before) - but the issue I'm struggling with and can't seem to find an answer to is the diagram or an idea on how to reseat the blades. Which blades go in which order and how I need to position them in order to get this lens back in working shape.

Anyone have any experience with this lens or other similar Cosina lenses that can help?

Thanks in advance.
