The Gambato Gran Sport series is a set of Argentinian 'derivatives' of classic Campagnolo models. While I am extremely unclear about the dates, I consider that they can be roughly grouped into three groups:
- a first series closely based on the 1953 Campagnolo Gran Sport. These Gambato Gran Sports possibly date from the late 1960s.
- a second series based, less closely, on the 1963 Campagnolo Record. These Gambato Gran Sports possibly date from the mid to late 1970s.
- a third series, that is the unlikely, bastard, child of a patrician 1967 Campagnolo Nuovo Record crossed with a plebeian 1984 Simplex SX1. These Gambato Gran Sports possibly date from the late 1980s and early 1990s.
The oddity is that, in each case, the Gambato models seem to date from about a decade after the relevant Campagnolo originals. It seems that the designs got lost in some kind of Argentinian time warp - perhaps in the boot (trunk) of a DeLorean.
