Marques reproduced were mainly Italian, like FIAT, Lancia, Itala, SAME and FIAT tractors, Legnano, Brixia, Cisitalia, and Bernardi, but French and German makes like Peugeot, Darracq, DeDion, and Benz were also produced (Castellarin 2002).
As with Rio and Brumm, many models were made in 'top up' or 'top down' versions, though Dugu models, while respected, were generally not seen as quite up to the standards of Rio (Sinclair 1979, p. 387).
