Need info on a flyback.

[Captain Video]

I´ve been talking to a guy who has some vintage TVs and related itens, and he said that even if I can´t find an original flyback to this set of mine, it's possible, with the proper information, to adapt another flyback of other tube type TV. It´s possible to put an equivalent flyback, it's what he said. Any thougts anyone? Has anyone here done something like this, or at least knows the probabilities of an idea like this be functional?
