That is the same car, it is chassis 001. The car emerged in Italy in the mid 1970s and was restored by Dagrada himself. It is debatable whether the current "spec" at all resembles the original car, or whether Dagrada up-rated various components to later spec during the restoration. For example none of the early cars ever ran Amadori wheels in the period. Also if you look at images of 001, which changed body style apparently many times in 1958/1959, the is little resemblance and certainly a much lower build quality of the body at that time. Any claims that this is the "Monza" car are also extremely debatable - more likely it was chassis 002, which until now is still "lost" - unless you believe it is the car in a museum in Sicily, however they will not comment on the origins of their car, nor reveal its serial number.
All of the 9 (possibly 10) front-engined Dagrada juniors were unique - no two cars are identical. They drew chalk lines on the floor to weld up each chassis, and each body was a unique creation. It is therefore fairly easy to distinguish between the cars in person or in photographs.
The 001 car passed through a series of Italian owners, it was first raced in the modern era at Goodwood in 2003, but was crashed on the first lap due to a suspension failure (photographs of the result widely available online). The car then passed to a Dutch owner who did a meticulous restoration. It moved to California last year, and the new owner is currently offering it for sale.
