Dalifol & ThomasTwin-De Dion Voiturette
An encyclopedia-described voiturette built in the Dulac factory at Montreuil-sous-Bois and distinguished by two separate De Dion engines. Accessible sources do not explain whether the engines drove a common shaft, separate wheels or another combining mechanism, so no synthetic layout is asserted. The cited 1896–98 span conflicts with a French account placing Dalifol & Thomas automobile production at Paris in 1898–1900; both are retained, and this early type is not merged with the materially different 1899 L'Abeille.
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.
No production total, chassis sequence, model split or confirmed survivor is known.
