Meyer Optik Gorlitz Trioplan 100mm f2.8 red V (M42)

[Bernard]

Hi there,
Need help. I have just purchased a Meyer Optik Gorlitz Trioplan 100mm f2.8 red V (M42) from eBay.
The aperture arrow on the barrel does not align to its respective values.
I decided to take the lens apart and fix it however I am stuck at the aperture barrel section and unable proceed further. I have taken some pictures of it.
Aperture placeholder A : I am unable to remove the retaining screw as the screw head is on the other side. Therefore i cannot remove the Aperture placeholder A.
Aperture placeholder B : I have removed the screw but unable to unscrew/pull the barrel apart.
Does anyone knows how to open this up?

Thanks !

Much better. The first post no pictures/link policy measure is to prevent spam on the forum. Not to make life hard for newcomers. I had the exact same experience a while ago
