Our model J has the red Bakelite agitator. I heard that they were the rarest of the three because if people had the money to upgrade they went for the Master. I like the porcelain tub. Our Chieftan is one of the newer ones like yours with the turquoise plastic. Funny, I just remembered that our 57 Pontiac came in three models, the Chieftan, the Star Chief and the Super Chief. We had the middle one. Our Master has the black lint filter agitator. Until we found that machine, John had a hard time believing that they made one for the wringer machines.
