You will be in rare company with a Sabre.
Mr Michael Potter started and grew a company named COGNOS that IBM bought out for a couple billion dollars. After paying for his divorce, he found himself literally swimming in cash and a love of airplanes. Every one of his aircraft has Canadian service or very strong connections to Canadian aviation. His Vintage Wings Collection is based at the Gatineau, Quebec airport. The clever part of his operation - every aircraft is its own legal corporation. If one plane needs to be sold, it can be wrapped up neatly and cleanly. Similarly, if one goes down or there is an insurance claim. Only that entreprise is effected.

They operate(d) Hawk One which is a Sabre. It is for sale. Maybe as it is being sold, copies of its documentation can be negotiated.
