Bizarre. I'm nowhere near as experience as a majority of people on here, but just when I feel like I've seen/read about most models, something new and unusual pops up. This looks like a cosmic case to me. Maybe something like Ref. 135.017, but the dial is unlike anything I've seen. It looks to be the same handset as the Dynamics from the era. It is either a decently put together franken or a rare/unusual model.
