I'm looking for the pre-Plasmat Symmars. Mostly these are f6.8 triple convertible or Doppel Anastigmat Symmars, but there are earlier ones of varying maximum aperture (f4.5, 4.8, 5, 7.7 etc) which may be labelled Anastigmat Symmar or just Symmar.
The last of the f6.8 lenses was serial number 3,337,403 so basically I'm interested in anything prior to that.
