I have a used ITT 6015 complete in factory zip pouch with head gear and mount. Comes with a pack of different camera adapters. I bought this unit used and do not have a data sheet for it. I can see no blems in the tube and seems very clear to me. I am not real familiar with these items but will offer a 24hr inspection period. $2050 shipped. I will try to answer any questions you may have.
