Jackman,
Could you post the type designation numbers?
It looks a lot like a 1964 yearmodel, not a '65..
Many little details as to why.. (Most significant is colour and the rubber-lip for the engine lid (over the cooler) and the clamps holding the rubber-list for the engine lid at the wind screen)
The key in the picture is genuine for the pre '65 models - It can either be ASSA or LM Ericsson
BTW - Todays reproduction of ign. key/lock barrel is a strange mix of the new barrel style and the old key style - I don't get why they did it like that..
Me thinks your 4door got a face lift in the 1991 operation..
