Certainly, this applied to HP.  Much of the equipment went back to
the 1959-1963 era, even as the line was closed down circa 2000.
Some equipment even used vacuum tubes.  Similarly, the cesium
beam tube burn in-fixtures were labeled "Varian" and went back
to 1960.  AFAIK, these were in use up to ~2005 when Agilent
sold (or maybe gave away) the business.  Can you say "cash cow"?
Supposedly one of the reasons for Agilent exiting the business
was that the equipment was so long in the tooth that they would
have to finally replace it, at an unacceptable capex cost.
Also, whenever you do this, you stand a good chance of losing
the recipe.
