That style of lettering is called Blackletter (also sometimes loosely called "gothic script", or "old English"), and if you do a search for "blackletter font" you'll find plenty of fonts that imitate this style.
You're probably looking for something specifically like Old English by Linotype or Monotype Old English which have been relatively popular for this purpose.

Or if you're looking for free fonts, UniFraktur is a free blackletter one which appears authentic but has a different style of capitals to what you're after. Meyne Textur is somewhat along the theme you're looking for. There are probably others, of varying quality.
