Leica 39mm Polarizer filter The condition is quite good, and it comes in a bag that appears to be from when it was sold. It seems to be from the same era as the Summicron, and the build quality feels very good. Attaching it to the lens is quite smooth, and the precision of the build is high. I confirmed that the LU filter effect was still normal. How about it for your collection?

Please check the photos for the condition of the glass, etc.
