Tamron Adapt-A-Matic 28mm F/2.8 Model PFH-28Au: This lens was available in four versions. We are not sure if the PFH-28Au model name applies to all four versions. Initially there was the first model which featured a relatively large optical layout and a metal knurled focus ring. Then there was a subsequent model which featured a rubber focus ring. The third model featured a complete optical redesign, was more compact and featured a narrower rubber focus ring, and did not have slots on the aperture ring for the aperture coupling band included with later versions of some Adapt-A-Matic mounts. The final version of this lens featured the slots for the later style aperture coupling bands. The first and final versions of this lens are shown above.
