I’m trying to understand the Italian system of registration numbers. This is for a 1937 bike. I know that the first two letters represent the area code. In my case SI for Siena. I would have thought that there would be 4 numbers after that, being the progressive number, but I have 5.
So the format is SI * 1 NNNN
Could it be that the “1” is a region of Siena? Or did they really sell 15,000 vehicles in 1937? If it helps the rear plate is in this format:
“From 1927 to 1932, Motorcycles used to have white digits on a black background and the provincial code was after the digits on the second line, in 1932 (to 1985) the motorcycle plates changed to a white background with blue digits, the provincial code was moved before the digits and like cars, Motorcycles used the Garamond font until 1951.”
I’m being told that the number 1 after the Siena code denotes the number of Moto Guzzis registered in that year. Followed by the progressive number.
I’ll try Facebook for more.
