Patrick Troughton in a dual role. The recons of eps 1, 2, 4, 5, and 6 available elsewhere on DM.

This is NOT the version that comes with the newly released, newly discovered full serial, which has been remastered. It is, however, good quality, and it will give you a taste of Pat Troughton in this dual role, then you can decide whether or not to purchase the full serial. :-)
