I'm in Canberra, Australia, and have a great deal of Jensen information handy. I can certainly try to help you if you have a query about the history of the cars or the company.
I'd also be interested to hear if you turn up a barn find. I'm sure there are lots of cars lurking about which I've never heard of, even though I probably know their original specification. If you see a car going to the crusher, get the chassis number before it's too late. I'd like to know about it to help refine my stats on survivors.
You can email me at firstname.lastname@example.org.
