Previously, Radar has a tattoo of an anchor on his arm, but here he is only considering getting one and Hawkeye and B.J. try to talk him out of it.
In "Check-Up" (#3.7), while Col. Blake gives Radar his physical, Radar strips to the waist to reveal a tattoo of an anchor on his right arm. The tattoo becomes the subject of the scene, from Blake remarking that Radar is not in the Navy to Radar flexing his bicep to make the tattoo jump around.
After Cooper excuses herself from the OR, Margaret switches operating tables to help Hawkeye. She should have changed gloves, otherwise she's contaminating a patient.
The Marine sergeant in Rosie's who is trying to dissuade Radar from getting a tattoo has hair length in the back that far exceeds USMC regulations. It lays over the back of his shirt collar.
Hawkeye reads out loud from a magazine about President Truman and Gen. MacArthur meeting on Wake Island. This meeting took place on October 15, 1950, and because it would make no sense that Hawkeye would pass along several-year-old news to his Swampmates, the unmistakable implication is that this is recent news, making it, indeed, 1950. However, there's no plausible way that B.J., Charles, and Col. Potter could be at the 4077th so early in the war, because the personnel they replaced (Trapper John, Frank Burns, and Henry Blake, respectively) could not have served long enough in Korea to have been rotated home or discharged only several months into the war.
Adding support to this is the fact that Col. Potter tells Maj. Houlihan that he and Mildred were married in 1913 and will be married 38 years come April, which means this takes place before April 1951 -- still far too early for B.J., Charles, or Col. Potter to have been deployed to the 4077th.

Potter says he has been married for 38 years since 1913. Previously he has claimed to be in WWI (1917-1919) at age fifteen. That makes him 11 or younger when he got married.
