F & S (Fichtel & Sachs) – Black, refers to a satin black, these were used on PreA, 1950 to 1955, all years except late (1954) 1500 Super.  Stamping information in unknown.

Shock Absorber Information from Joris Koning

Below are some of my observations over the years from original cars, factory documentation and discussions with people who have been around these cars for years and have competed at the highest level.

  • Pre-A; no idea
  • Early A; Fichtel and Sachs, have Porsche part # and are dated on the bottom eye
  • Later A; Boge, .1 part number and possibly black, not sure
  • T-2 optional, Koni, reddish orange with date and "porsche" embossing
  • Mid B; Koni, grey in color with date, 'Porsche' embossing and part #
  • Late B/C; Koni, blue withdate, 'Porsche' embossing and part #

The factory service bulletins give some more clues with regard to the Boge's. Bulletin F12/61 states, "In rahmen der technische weiterentwicklung wurden ab obengenannten einsatztermin in alle fahrzeuge mit motor typ 1600 verbesserte Boge-stossdampfer eingebaut" Loosly translated this means that through further technical development, as of above date improved Boge shocks will be used in all typ 1600 cars.

Bulletin F10/63 states that as of 13.3.63 Boge's will be used in the 1600S and S-90 "Zur kenzeichnung sind die Stossdampfer braun lackiert" For recognition they are painted brown.
