A home-built Czechoslovakian
car that was constructed by Ing. Gajdos who worked for the Tatra Koprivnice
car and truck company. The initial power plant was unusual, it was the
2472 cc V8 engine from the Tatra 603 effectively cut in half and uniquely
for an F3 engine it was air-cooled, the transmission came from a Fiat
600D. Three Delfins appeared at a race in 1964 at the Sachsenring that
mixed a largely East German field with 8 or so contemporary western cars.
Sadly, given their very unusual components, they weren't noticeably competitive.
The next appearance (assuming it was the same car) was at a race at Brno
in 1966 when two cars were entered but did not finish, one was listed
as a "66" the other as a "65" indicating there were
two different designs. After this a single car arrived at Hockenheim in
1968, no engine was listed so it is not certain that Tatra still provided
the motive force, no result was achieved. The final appearence for a Delfin
was at a race at Neubiberg in October 1969 when it failed to finish, for
this race at least the motive power was courtesy of Skoda.
