I've always found G-INFO easy enough to use. Perhaps because I'm familiar with it. I typed GREAT LAKES in the

I expect that's about it for CAA registered aircraft -->

Bear in mind that FAA registrations are commonly seen on US manufactured aircraft in Europe.
There is also a Great Lakes UK website which might be some help.
