I still keep a Vespa 400 registry which is probably not very current as owner don't register or update or don't know about it.
Hank Pinckey of microcar club also keeps one and we coordinate data from time to time but he does not have online registration ability.
Here is a link to form which you can enter info online and it will send it to me and I can add or update the word table and send a copy back via email. It is not for comercial use, just for owner/restorers info and I only send it to registrants. Link is: [
