HISPANO-SUIZA T49 BARCELONA

Chassis only listed, various customs.

Later version of the small Spanish 3.7-litre ohc six (introduced 1924) with cast iron block and detachable head, though specifications are otherwise vintage Birkigt. Two wheelbase options, and enlarging the engine makes for a higher axle ratio, 4.2 as against the 5 to 1 of vintage models. UK-available up to 1933, and central change on late examples.
