Wow, thank you! Alas, most of Victoria's episodes are lost. Her only full surviving serial is Tomb of the Cybermen, which is her second appearance. (It's also Matt Smith's favorite serial. You can definitely see a lot of Troughton in his performance.) There are a few other partial serials, and of course reconstructions, which is how I experienced it. I really love Two's whole era, though, and would recommend anything from it.

I'm glad I was able to get the feeling of the story across even to someone unfamiliar with it!
