BorchardingDreirad
Borcharding & Co.'s own open two-seat three-wheeled small car, represented by the contemporary generic German identity Dreirad because no factory model designation survives. Published marque histories establish the 1924 build but preserve no chassis layout, engine supplier, displacement, output, transmission, dimensions, price or quantity; those fields remain unknown rather than being borrowed from the later Mollmobil. This was a distinct Borcharding design and not the Moll-Werke car the company assembled after becoming a Moll agent.
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.
At least one open two-seat three-wheeler was built in 1924; surviving sources do not establish whether it progressed beyond a prototype or give a production total.
