I agree... Those 27" B&W sets were COSTLY, and might have been priced about the same as a mid-60s roundie color set. So that's a pretty clear choice: Trade a few inches of picture size for color. I still saw later model 27" B&W sets in schools and as bowling alley score monitors where a big screen was needed, etc., into the late 70s, and those were probably the last ones made in the late mid 60s.
