I recall the Cosmic Wind G-AYRJ "Little Toni" also carried its former US reg while being campaigned on the F1 circuit in the 1970s - remember seeing it in the Tiger Club hangar at Redhill (and I believe it's back in the UK now along with "Minnow" so we have all three of the original LeVier Cosmics here to keep Pete Kynsey's "Ballerina" company!)
