BMW 3/15 PS DA 4 open-top two-seater

In the very limited product range of the DA 4 model series, only the favourably priced wood/steel bodies of the two-seaters and the touring cars covered with leather canopy roofs survived as open-top versions. The bodywork remained unchanged by comparison with the DA2 models and only the front rigid axle was exchanged for the newly developed swing axle.
