The type "B" is the more elaborate all enclosed cup.

The Ford people call the Type "A" the Bendix-Weiss Joint, and the Type "B" the Rzeppa. There was a third joint very similar to the Bendix called the "Tracta". All three styles of joint were also used in Jeeps, Dodge VC+WCs and Marmon-Herringtons. (In fact, the Rzeppa still continues to be used in the front end of many 4wds today, but for some reason is now called a Birfield joint.)
While the Rzeppa is the more time consuming to manufacture, it can be used at higher angles than either the Bendix-Weiss or Tracta, and has better wear properties as it shares the torque over a wider area, but is more particular about lubrication. (Hint: remove the set screw in the end of the stub axle and fit a grease nipple and lube with hi-temp lithium grease. There is a spring loaded pin on the inner end of this threaded hole, and centrifugal force will spread the grease into the ball channels.)
Good stuff, Bob!
