Setchell-Carlson seemed to make the same set for a few model years. Either that, or the CRT was replaced under warrantee.

You're probably right.

I was studying the Sams schematic last night when I realized this TV has a Series 60 horizontal(F) module instead of the original series 2. The series 60 replaced the original 6BQ6, 6W4, 1X2, 12BH7 with 6DQ6, 6AX4, 12AU7, 1G3. The series 60 seems to have showed up in around 1959. Same basic circuit with updated tubes. Pretty neat how SC had these newer modules designed so they were backwards compatible, and apparently shops took advantage when swapping modules in the customers home.
