When the Sacramento school on Riverside Blvd (the one that is listed on the original brochure and described as the Tracy's second school) changed hands (or whatever the transaction was) in the 60's, the students, including most or all of the senior students, all trooped over to the Fulton Ave. studio, or so I understood (there were some satellite practice groups that I heard about, but I don't have any detailed knowledge of them). A year or so later (late 60's) I began working out at the Fulton Ave studio. That studio was seen to be distinct from the Tracy brothers at that point, but obviously there was an overlap; really a continuation. Workouts were lots of falls, rolling and diving falls, as mentioned, including a judoka throwing us so that we'd be familiar with that sort of thing, no breaking that I know of, lots of technique practice including the "line" and two and 3 man attack practice.
Forms were in the picture by the late 60's; Form 1 through 5, Book Set and Two Man set (they were two very distinct forms, not "the same thing" as I've heard many years later). There wasn't padded contact sparring like there is nowadays, just shin and mouth guards. "No contact" (always a misnomer when the blood begins to boil

) was the rule in general classes, but you could negotiate with your partner for whatever level of pain you wanted. There were separate brown belt classes which included blackbelts, and there may have been a black belt class at some point, but it was a relatively small population of students so it was as far as I know really a senior student class. Saturday classes were more of the same, but there was frequently an emphasis on "bar room fighting" ie, objects in your way (objects to use

) and that sort of thing.
There was bag work, hanging bag and held bags. Makiwara work was left up to the individual to construct and use, although I remember some sort of rig in the back that was used as a makiwara.
The above doesn't answer the question exactly, of course, but it gives you a sense of what the overlap/continuation was.
