Hi Norman,

The number stamped in the chassis frame should be the same number as the “Car Number” on the ID plate on the bukhead. All LG45 had a car number (which is the chassis number) starting with 12xxx. The engine number has the same format. The 69.35/6 means nothing to me and I doubt it is a factory number but I will check for you. What is the Car number on the iD plate and I’ll check in our records to see if this number has any relevance. (I am the Assistant Registrara of the Lagonda Club) If you prefer you can email me direct on len.cozzolino@lagondaclub.com

I look forward to hearing from you
