The Fairey Rotodyne is another favorite of mine...
Sometimes this aircraft is refrerred to as a gyrodyne or gyroplane. Clearly, it's a later cousin of the early autogiro.
A few different toy manufacturers produced examples of the Fairey Rotodyne. Without exception, they're all VERY collectable.
Here are some of favorites - a few of these have appeared in other threads, but I'd like to consolidate some of the photos here:
Tomiyama Vertical Liner for Sears - came in two versions, one with and one without retractable landing gear
Bandai Vertical Liner
