The DCA "S" model was for sale in recent living memory, don't know where it is now. The following link gives our history with them.
Beech V35A Bonanza VH-CAG
It interests me because Bill Lord gave me my first introduction to the Chipmunk and aerobatics many years ago, and I've met the glider pilot. Still going I believe.
EDIT: I hate to do it Clinton, but I just can't help it. Hope you and your Bonanza are well.
