When I am trying to cross reference, I have found this website useful:
http://www.bunkerofdoom.com/xfm/index.html
This site includes a number of Stancor, Triad, Thordarson etc catalogs which provides coil resistance, inductance, deflection angle and TV part numbers which helps determine equivalent.
It might take a little digging. I also find the Sams TV set documentation for replacement parts useful.
