I also have discovered that the below listed episodes are missing from my collection. BUT these episodes are from the later seasons of Father Knows Best and they are actually REPEAT episodes from earlier programs. My guess is that they started out the show as the now older family "remembering" back to an earlier episode at which point the repeat of the original episode plays. Well, now I have these original episodes but what I don't have are the "Remembering back" episodes where they start off the show by recalling an earlier episode. Does anyone out there actually have these listed "remembering" episodes? Not the original episode, but the "remembering" episode #'s listed. These programs were all titled by the same name when they first played, so you have 2 shows with the same name in each of these cases here. Many people think they have these episodes because the title's the same, but actually these episode #'s are the later remembering versions. This is what I'm looking for, not the original episode but the remembering later episodes listed here. Let me know if you have these shows, I will gladly trade you for them, I have a very large collection of shows. Here's the "Remembering" episode #'s I'm looking for:
162. 5-29 162 30 Mar 59 The Art of Romance
165. 5-32 165 20 Apr 59 The Promised Playhouse
167. 5-34 134 4 May 59 Live My Own Life
170. 5-37 170 25 May 59 Margaret Goes Dancing
185. 6-14 185 11 Jan 60 Father, the Naturalist

Also need this regular episode if you have it:
202. 6-31 202 16 May 60 Not His Type

Please let me know, I'd be happy to trade with you. :)
