This eyecup is NEW but has a slight brownish discoloration. Maybe is can be bleached.
The high res marco pictures make it look worse. It looks very nice and hard to see when on the camera.

OEM HIGHEST QUALITY! ARRIFLEX RUBBER EYECUP***NEW


 BOLEX EYECUP EYEPIECE for H16 EBM H8 REFLEX REX-5 16MM MOVIE CAMERA + OCTOMETER



 Informative installation pictures above onto an old parts camera. Instructions below.

Put the hot eyecup partly on the eyepiece disk, then twist the eyecup sideways + use tiny pocket screwdriver to pull up the rubber over the disk, then twist again to install the last of the rubber over the disk. Now you are done. Twist the eyecup to desired position. Careful not to stab yourself with the screwdriver or burn yourself with hot water. Please use common sense.

Due to the nature of the molding process they may have minor marks on the rubber but assuredly I say to you, they are NEW.
