Ok, it's 56 euros and the rest seems to be in good condition is it worth the money you think?
I am new to this forum btw and the insert picture function is a bit different compared to other forums |

For 56eu take it without hesitation, it is a great lens, the engineering on it is very heavy duty and I cannot imagine this causing any trouble to the big steel blades in this thing, the aperture mechanism makes a sound like a bolt action rifle, very robust and strong.

I've had a look for the links to the repair sites and can't find them, they must be on my laptop ? I'll keep looking.

Indeed seems identical to my Chinese m39-m42 adapter. Not a great one - sharp threads make handling it unpleasant, but it works. At least you'll get it quicker than the one from China. |

I have a serious issue  the lens seems to be filled with fungus. At first it looked totally clean until I held it in a powerful light. I made a picture of it. I am quite good with electronics and mechanical stuff but is it possible to fix this? My first thought was fungus. The rest of the lens is in great condition.. smooth aperture and focus.
Picture
kind regards,
Rens

Ouch that looks nasty!  i haven't seen as much on any of my Tairs but it might be repairable, have you taken any shots with it yet? if so does the fungus show?
Personally if i had seen that much fungus i'd have looked for another, such a shame as they are superb lenses.
One thing i have noticed is that the Photosniper metal cases seem to attract condensation so i usually drill some vent holes in the metal case |

many thanks for the info. The fungus seems to be very thin(don't know if it matters) but I immediately noticed that the lens is quite old because when I tried to unscrew the smallest screw(to test if I had the right screwdriver) it broke off when I screwed it back in...
I have successfully removed it but now I am one screw down..
Nevertheless it might have been that the screwdriver was bad(cheap) and I will probably move on and look for a replacement screw at a watch shop or something.
What works best to remove fungus? vinegar or something else, I read the topic you send me but people seem to disagree with each other.

I can say only my opinion I used strongest chemical what I can buy you read it in given post. In general might be everything is same good due matter only how you will store lens in future. If lens properly stored fungus will not come back, if not , no matter what was cleaning material fungus will return. I think this is main reason about different opinions and why even simple water works.
Quality screw driver and WD-40 is essential , soft garbage from supermarket not works as you experienced it already. Buy best one in quality hardware shop it will serve you well for decades.

ok,
I decided to give it a try(nothing to do tonight). I got pretty far(according to myself) and the front lens element is off. Now I cant seem to find the mechanism to remove the iris and the back element from the lens.
I am at this step:
this is the back of the lens.
Update:
WOW!
the front element was extremely easy to clean!!! I took a microfiber cloth and wiped it right off!! tomorrow with vinegar and it will be clean again no marks left!
kind regards,
Rens
