Laurin & Klement mod. B2 - 400cc - 1903 year
The total production of the factory was approximately 3000 units, not many even in those days. Compare for example, with almost 20000 De Dion tricycles built in just over five years.
There are very few survivors today, almost all confined to the country of origin.
