Help me identify a season of M.A.S.H.

So I’m sort of interested in buying a season of M.A.S.H., and I’m trying to pick which one. I’m watching it right now on TV and there are a few episodes with a particular cast that I’d like to watch. Particularly, there’s a season with Colonel Potter, Winchester, Honeycut, and Radar. I know this must be in the later half of the series because Potter is there, and it can’t be at the end if Radar is still there, but what season is it?

Season 6 (which is the first one with Winchester) or 7.

Season 8 had Radar’s departure - he was in two episodes, but that’s it.

According to imdb.com, Hunnicut and Potter joined the series in Season 4, Episode 1: Welcome to Korea, which aired in September, 1975.

Rader left at the beginning of Season 8, in a two-parter: Good-Bye Radar, Part 1 and Good-Bye Radar, Part 2, which aired in October, 1979.

David Ogden Stiers began as Maj Charles Emerson Winchester in season 6. Corporal Walter Eugene “Radar” O’Reilly, as played by Gary Burghoff departed the series in season 8. Harry Morgan, as Colonel Sherman T. Potter arrived in season 4 as did Mike Farrel. I tried to do the math to find the one season you are looking for and it hurt my head. If you could give me an episode you are looking for I could find the season.

So seasons 6 and 7, or failing that, 4 and 5. Thanks!

oops - missed the OP’s reference to Major Winchester. As SSgt Schultz says, he arrived in Season 6, Episode 1: Fade Out, Fade In (20 September, 1977).

So the episodes the OP is thinking of must have been in either Season 6 or Season 7. My recollection is that Burghoff was wanting out during Season 7, and some of the shows towards the end of that season he had only minor appearances, supposedly because he was on R&R in Tokyo. So probably the OP is thinking of Season 6.

appleciders, why not cruise the imdb database on MASH for Seasons 6 & 7 and see if you can find the episodes you’re thinking of?
