The 6F32 is an RF pentode and is for replacement purposes. The Mazda Octal base was not fitted to new types in 1956. The datasheet gives the design purpose as modulation and timing applications.

The Mazda Octal base has the same diameter pin circle as the International Octal but the central spigot has a larger diameter.

The classic envelope is 32 mm in diameter, and excluding the IO base pins is 80 mm tall.
