Although known to many as 01, the correct designation for the aircraft is 101. Initially designated 01 the serial number was changed to be a 3 digit number as the 2 digit number was not easily handled by computer systems of the time.
The fact that the Model number for the production aircraft were to be 100 (basic model),101 (French production) and 102 (UK production) were also possibly a factor why many though and still think of the aircraft simply as 01

The gestation period of the aircraft was so long that almost inevitably its design and indeed its specification changed after the Prototype design had become frozen. Hence the Pre-Production aircraft had a different wing plan form, more fuel, a higher engine standard, a "glass" visor rather than metal and a different intake system.

In fact the intake system on the British Pre-Production aircraft was even different again coming out very close to the final standard. It would not be true to say that the Pre-Production aircraft where superfluous but they were in a sense a luxury although probably necessary to keep the momentum of the project going. The British Pre-Production aircraft did about 600 hours and the French some more but in truth their contribution to the whole exercise turned out to be rather less than it was first intended.
