I suspect that most lenses made by Carl Zeiss for Rollei cameras
received the "HFT" engraving on the lens ring instead of "T*", there
is no doubt Carl Zeiss Oberkochen made a lot of lenses for the
SL35/2000/3000 QBM Rollei mount, for the Rollei SL 66/E/SE and for the
Rollei SLX-6000 cameras with the term "HFT" and not "T*", CZ even made
the Planar 2.8/80 for the Rolleiflex 2.8F "Platin" TLR camera
engraving the term "HFT" and not "T*" on the lens ring.
These are some samples about exotic lenses made by CZ Oberkochen for
Rollei SLR 35mm cameras like the Carl Zeiss 15mm f3.5 Auto HFT
Distagon and similars with the term "HFT" and not "T*":

These are samples for the SL66 (click on the red arrows to the right
of the lenses diagrams and data, the exotic ones specially) :
