ok friends,
when you understand that with the good you can not get anything, move on to the bad. Here are the photos of the lens opening, after making two holes in the plastic ring, opening it with a watchmaker's tool, lens cleaning and reassembly.

Thanks blumoon722. I have to check if they are available in Italy, because in addition to the biblical times to get them from the states, I should still consider shipping costs. I'm trying with anything I have available, but it seems literally soldered

I confirm that this has no opening at the sides, it is visible screws at maximum extension. It is practically impossible that it should be done from behind, so the only possible problem is that it has been soldered or maybe some old owner has glued it

neither to her nor to her uncle. I was very nervous when I wrote this post and I could not sleep. As a result, since I could not finish cleaning on the 28th, I started to disassemble the M 55 1.7, and at 4:00 AM, it is not the right time to do these things.

yes, this is it. I had already found it on an Australian site .. now I just hope it is the right scheme, even if I have some doubt. The shell enclosing the lenses has a sign that makes it clear exactly until the point of the thread was screwed, but respecting this scheme the metal "plug" does not screw to the same point. Very strange

Yes FozzFoster, unfortunately there is not. I had already consulted the db and I saw that it was absent. It seems however that I found the exact scheme on an Australian site. I hope it is reliable

Hi everyone, this is my first post and I ask you to apologize if it is not the right section to post it, and even more I apologize for my bad English. I write to ask if anyone has the assembly scheme of an old pentax A 28mm f2.8. sn.5332597 I'm trying to open to remove a mold. the problems I have at this moment are two: on the front I can not remove the front cover ring, while the back I managed to open and clean it, but in my absence my niece "played" with the removed lenses and now I have the doubt of having mounted them by reversing the position of the faces. I'm sure the order of arrangement is correct but I'm afraid of having inverted the inner face with the external one, and in the absence of the assembly scheme I do not know how to do it. I have already searched on the page dedicated to the lens here on the website, but unfortunately it is not present. Can someone help me? also someone has any idea why I can not unscrew the front? thank you in advance. Dani
