Little Toni has a fairly straightforward history as does Ballerina although Ballerina has had a rather chaotic life at times.
The Chino airframe is Miss Cosmic Wind whiich has a shoulder wing and her history was part of the mystery as at one time this airframe probably incorporated the wing from Minnow. The history and final fate of Minnow appears to be linked to the history of Filly which was built by Robin Voice in England.
I think I have most of the history pretty much straightened out now but there are a few areas connected with the period when Milton Blair owned Cosmic Wind airframes and parts which may never be completely confirmed.
