Purchased new in 2019. It has been sent for manufacturer overhaul twice. The handle knob is a Studio Ocean Mark AG41 (purchased September 2025). The original parts are not included. There are signs of wear and tear as shown in the photos, so please only purchase if you understand this. There is some slight play and a bit of a clicking sound, but it does not affect use. In my personal opinion, the mechanical condition is good. Thank you very much.
