I was sent a scanned image of this brochure by Richard R Fuller of Jacksonville, Florida. Richard's father was one of the founding associates with Gyro Transport Systems (GTS). When the company dissolved, Richard's father was offered a job at American Airlines and the family moved to Tulsa. But the younger Richard kept a lot of materials, including an 8x10 glossy of the Gyronaut X-1 signed by Alex Tremulus to his father, and the product brochure for the Tuscan. Richard kindly scanned the brochure for display on the web.
This raises an interesting question: Who holds the copyright on this item? I do not know. I feel the display of the material here is justified on academic and scientific grounds, but if any parties believe they are the legal copyright holder and wish me to remove the item from the Internet, they should let me know.
