Thanks Don, for your input on the subject of Engine and Frame numbers.
I have a couple of bikes that fall into the odd numbering system used by Moto Guzzi and the 50’s.
My Super Alce has Engine number AV 97221 and Frame number AV 30716. The numbers match and I know that the bike was built on the 14th January 1952 (as per the factory records). My understanding is that the numbering system used in the early days was a straight numerical system which would imply my Super Alce was the 97221 engine built. This sounds like it might be correct ie 97221 motors made between 1921 and 1951 equates to 3200 motors per year, 270 per month.
My question is, “does anyone know how to decode the slightly later numbering system as used for the Cardellinos?”
I have a 65cc version with frame and engine numbers DIR 02, and a 73cc version with engine and frame numbers BZT 07.
How did the numbering system, that started at A 00 AA and ended with A 49 GZ for the 65cc version, and started at B 00 AA and ending with B 24 FF for the 73cc version end up as DIR 02 for the 65cc and BZT 07 for the 73cc?
I look forward to your replies.
Cheers
Phil

I got the numbers originally from a Dutch Guzzi Website and then cross-checked at the local Lusso Veloce (Italian Import Specialists in Ellistown Leicestershire) my local 'dealership, where the have a copy of Mario Colombo's 'Guzzi Bible'. This confirmed the numbers I had found on the Dutch Site.
