I was one of the first to enroll in May 1979 and it actually was called "Dan Howards World Gym" in the beginning.
There were T-Shirts and shorts with the familiar World Gym Ape Logo selling in the front glass case, of which I bought and wore some.
Kal Szkalak was managing and the first summer it would usually be just Kal and I in the afternoons,after I was out of class, unfortunate for me, since Kal always wanted to use me as added ballast on some movement..
Kal actually had a notebook at the old Gold's, and in it was making sketches and notes of all the equipment, for Dan to duplicate at the Fountain Valley Gym his wife funded..and said he feared Joe would see him and kick him out of the gym for thieving his ideas..
And yes..Boyers equipment did pop up a little later..but it seemed heavily Arthur Jones influenced with cams and no one used it..in the picture of Dan thats Boyers BodyMaster Line in the lower right, gold in color.
Dan would usually be out back in overalls fabricating more pieces..it was a very quiet summer..
Also, DH was a judge at the O in 1980..and at another time, he and Arnold briefly had started a company, "The Association". So there was a friendship. Dan place Arbnold 2nd that year, and Arnold would not speak with him after that. Dan later said as a judge, that Arnold of then was not competing against the earlier version. In the contest of course. In peoples minds....another matter...
