W. G. Bell's sole Rochester design was advertised in 1920 with alternative J.A.P. or Precision power. Surviving references do not establish displacement, output, body details, transmission or whether more than prototypes were made; the record therefore represents the documented design without claiming series production.

This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: attributed imagery. Fields we cannot source stay empty rather than guessed.
