I  wonder if the tele tessar was a true  tessar   design  or  just a  use 
of  'the name' ? I have seen   snipits in google referring to it being a true 
telephoto...  with a true  tessar formula  lens  IS NOT.
ok  the  norm   for the hassleblad was a80 mm  f  2.8 planar...
in the rolliflex   the tessar was the entry level lens... the  planar  the  
my  first  'real' camera was a 1933 rolliflex  with a   f3.5 tessar.   not 
bad  at  all  but a little soft  wide open.
I still have  this  camera. and the low  shutter   speeds are a little  
slow  but OTW   rest is   fine..
In  HD  I  bought an argus  c3   from my  geometry teacher  for   $8   and 
used it a lot   more  shots  per  roll and  would operate  eye level  and 
had a  pretty  good  split image rangefinder.. the   lens  was  decent too.
when I  went in USAF  sold   the  C#  to  my  brother but  kept the 
rolliflex  (  wish I had   saved both! as  the argus  shot  some of  my   first  
press  work)  adn  when in USAF   got a  SLR.
