Kenko MC YA 3 for Black and White Film - Filter Color: Orange - Brand: Kenko - Model: MC YA 3 62mm It has likely been stored in a dehumidified storage box for over 30 years, but for some reason, mold-like stains can be seen on the surface. I have refrained from removing them to avoid fingerprints, and will ship it in its current condition, inside a Nikon CP-3 case.
