Sourced production or model lifecycle range used by the main catalog timeline.
ClarkmobileRunabout
Clarkmobile Company's sole documented production family. The engine sat under the seat and drove the rear axle by shaft; the hooded front compartment was luggage space rather than an engine bay. Wheel steering, shaft drive and a front hood were promoted as advanced features in 1903. Wooden wheels wore Dunlop tires, price was $750 and the car was advertised as the 'Unbreakable Clarkmobile.' A local retrospective mentions an earlier experimental two-cylinder prototype, but no evidence establishes it as a separately marketed production model, so it is retained in marque history rather than counted as a second model.
Dates with their meaning intact
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.
Approximately 100 automobiles according to a 1950 Lansing retrospective; no surviving factory serial ledger confirms an exact total.
