Tominon 105-how to mount the blades?

I had the tominon 105/4.5 taped to a tube(in reversed position) but attached first to an adapter. I forgot that when trying to remove-holding at tape-level and not adapter. so i had the aperture-part in my hands blades(10) mixed all over.
I need instruction how the blades must positioned on the ring which will then be inserted with pin in the hole of the other part.
there are tree possibilities A, B or C of mounting the blades since one side is roundshaped the other not. Tried endlessly, could mount but aperture ring doesnt rotated. maybe there is an instruction where the 10 pins must be positioned before mounting the ring inside lens-front.

Should have read manual before. Solution is on page 133. here it is. second smaller document was uploaded as standard since i didnt want uploading another one... a bit confusing. both seem to be the same size. converted from tif to jpg.could be i err.

From my experience, tweezers with curved tips will do a better job.

I only know my tools were not ideal. will have to clean the blades first. I will use rubber-gloves and not textiles. DUSTfree working...
are the instructions you gave identical to Polaroid manual? didnt yet study in details.

Most old lenses with many blades are arranged in similar manner. You don't need to read the manual if you have experience on putting the blades back.
