And the Gossen is a legendary piece of kit too.
They are all missing the "rabbit ears" of
AI/AI-S lenses, and are later
model Series E lenses (they added the aluminium ring to make the Series E lenses look nicer).
Hmmm, interesting ....
The rabbit ears were removed some time after they introduced aperture indexing, which was the way that the very early lenses communicated the aperture set on the lens by the user back to the camera body. On
AI lenses there's a little ridge on the back plane of the lens. Pre-AI lenses had solid "rabbit ears" with no ridge, and
AI lenses with rabbit ears had cut outs in the rabbit ears, then they dropped the rabbit ears.
E series lenses, to my recollection, did not have the aluminium ring, and had "SERIES E" engraved in white on the ring surrounding the front element of the lens, but it seems that this may have been only for the earlier versions. They were also designated as Nikon, rather than Nikkor, and they were introduced to partner the EM body, which was intended to be a cheaper, entry level SLR.
Looking at
Ken Rockwell's site, he says that the later Series E lenses had the aluminium ring; the earlier ones were all black; my recollection is consistent with his description of the earlier ones. If you look at the images here, there's no rabbit ears, the
AI ridge I describe is clearly evident just below the f/11 mark on the aperture ring, and on the black lens, you can clearly see the "SERIES E" engraving on the front of the lens, towards the left on this image. Also check out
this site, which contains some wonderful information as well.
