Good day everyone I rewrite my post as I was unable to publish the photo.
I have restored the optical part and the iris of the sonnar, but now I am still in reassembling the helical part. I can not understand what is the assembly sequence of the three elements that are seen in the photo. Can someone please help me ?.
Thanks

cesare,

I can't help with your lens, but I still wasn't seeing your photo so I quoted you to get it to show.

I guess, Middle one, the inner helicoid marry to the rear base at first, then connect them to the front housing.

Thanks for the tip, but I've already tried. The problem is getting the pins inserted into the guides of the helicoidare

hold the inner helicoid at a special position, let it turn together with the outer helicoid towards the same direction, this way might work. BTW, did you polish the lens body?

Thanks for the advice, I'll try. Yes, I polished the lens body with this German product: "ako hochglanz-politur" fur alle blanken metalle.
