The spitfire in the advert is possibly registered in Italy, judging by the lack of form of any other letter(s) or possibly Spanish or even French? But reading the specs below, the registration number could be pre the regulations below.
ITALIAN :There are 7 digits in the registration code and they are split into three – two letters, three numbers, and two letters. The letters 'I', 'O', 'Q', and 'U' are excluded from Italian number plates. In 1999, the registration system was restructured, and the numbering begins from 'BB 000HH'.
SPANISH; The first four numbers of a Spanish Number Plate are a counter which runs from 0000 to 9999. The next 3 letters are a sequence which started with BBB and will finally end with ZZZ. As at May 2023 we are up to MGY, so once there have been 10,000 registrations the letter sequence will change to MGZ.
FRANCE : The registration plates issued since 2009 use a XX-NNN-ZZ format, composed of a series of 7 alphanumeric characters: 2 letters, 3 numbers, and then 2 letters (e.g. AB-126-FD).
