The former N45091 was sold in 2012 and moved to Ontario, Canada. Her new registration is C-FNMW. Shown here before her trek north:

New owner Michael transitioned to tailwheels in his “N”, here is a video of his first solo takeoff: http://www.youtube.com/watch?v=7oS8dMUJITc

This is the actual aircraft that buzzed Cary Grant in the movie “North by Northwest”. Here is a photo on the movie site that clearly shows the registration number:
