You can get a redacted copy of the Blackbird -1 on the internet, but I've never seen one for the U2/TR1 manual.
Anyone after a U-2C/F Flight Manual, there is a 1967 305 page copy available on CD. Forum policy prevents giving a link so PM if you want the link as to where to place an order. Hard copy also available from the Sth. American river. No TR-1 though, just C and F.
