Century Tele-Athenar f/4.5 385mm Telescopic Lens, comes with everything shown in the pictures. From what I can tell, the lens looks to be in good shape, I had a bit of trouble getting a really good picture of it. I'm asking $135 for it and will include free ground shipping within the continental US. Worldwide shipping is available, message me and I'll get a few different shipping quote you can choose from.
Very nice piece of equipment. In general to get bites on something like this you’re going to need to specify what lens mount the lens has because this will determine who has the gear to mount it. Making a wild guess here the rear cap looks a lot like it’s a “C” mount which was a common screw mount for many early 16mm motion picture cameras. The other thing suggesting the C mount is the maker, Century. They made a lot of high quality specialty lenses for 16mm movie cameras back in the day.
Thank you very much for the info, I appreciate it. As I said before, I'm an audio guy, so any advice regarding the photo and video gear is very much welcome.
