I wonder if the half cases prevent light leaks associated with rubber foam seal breakdown around the film door.

In general, the Version 1 Super Takumar 135mm/3.5 lenses have "4" marked on the aperture ring between 3.5 and 5.6, while the Version 2 lenses do not show the "4".
I own a lens with a serial number in the 17xxxxx range that appears to be Version 1, but others in the same range may be Version 2.
Based on things I've read, the transition may have occurred around 1967.
