You may ask Simone about the engine number. I only give information about the machines from our Vincent register to members of the Scandinavian Vincent Club.
If you can prove that you own a machine and are a member of SVC, I can provide some information. The information I have is engine number, Ufm-Rfm number and in many cases registration number, as well as on certain machines, old and current owners.
Simon has a copy of almost all information in our register.
