Antique surplus components from NASA programs such as Mars Observer, GEO Star, or Telestar date from 1987 to 1991. Each package has its original tag listing the description, quantity, date code, etc. for the contents, which are mostly precision resistors. We are selling these to those who want to collect a piece of antique history (34 years old and some even older). Every one of these component bags cost NASA much more than our price! New very old stock – sorry, we cannot select specific programs, parts, years, etc. Price is for 1 package, not the 3 shown in the pictures.
