I have just found out that we own a Jaguar MkVIIM that was made from Oct 1954 to July 1957.

I would like to find out how many were made and how rare they are.

We also have the Jaguar Mk IX used by the Dutch Royalty on their visit to Australia
roughly 20 years ago and am trying to find if there were any photos taken
with them using the car.

Any help or ideas of where to look for the info I am chasing would be appreciated
