I have a neighbor that is friends with Raymond E. Umbaugh's daughter. She had in her possession a plethora of articles about her father ( designer of the Air &Space 18). I have scanned all of the articles for preservation to the Gyroplane sport. If anyone wants them send me an email address in PM and I'll send them to you. Interesting stuff.
