item #100mmf45cintarArgusC33. There are some spots inside the front lens group. The blades are oiled. This lens would need to be cleaned inside if you bought it. Condition 8-. Comes with the original hood. I am almost certain this is a C33 lens as the mount is different than all the other Argus optics that I have. I am not 100% certain but fairly certain this fits a C33 Argus Camera.
