S. Smith and Sons Ltd is the supplier of the tachometers installed in the Volvo 1800 series. Between 1961 and 1973, five different versions were installed.
They differ in their external design, the dials and the electronic components. The mechanical part, however, is the same in all versions.
Warren Townsend has taken the effort to document the versions, not only to describe them carefully, but also to present them with illustrations.
