This listing is for an original letter that was typed and signed by American aviator Darryl Greenamyer. The letter involves him trying to get paperwork on a Rolls-Royce Spey 201 engine with the hopes of installing it in a Lockheed F-104G. The lot also has some paperwork that he acquired from his inquiries. This was acquired in a storage locker auction. There is some wear from use, age & storage, but overall it is still in good condition.
