Is this MKV original one of Jaguar, or modified one afterwards?

The limousine, “stretched” white Jaguar looks like a Mark V with a stretch section added later. This was a relatively common customization done on cars in the 1960s for people running limousine businesses. I have never heard of a limousine Mark V done by the factory.

Thank you for the comment. You are reliable.

Agree, definitely not done by the factory.
