REPS / SCOTT: Good call but let me add one more!
That definitely looks like SPRAGUE to Arnold's immediate left.
That leaves two who are unaccounted for ... the two guys to Arnold's immediate right.
But as somewhat of the imminent know-it-all regarding all things bodybuilding related and a quazi-intellectual when it comes to Quantum Mechanics, I have to add a few very short comments about the one individual in that photo who seemed to enter every contest ever held within the LA Basin back in them good old days.
And believe me ....... there were very few BB Contests within that basin with the main contest venue being the Embassy Auditorium in Downtown Los Angeles plus the small events held on Venice Beach on an outdoor theater stage that is no longer there.
Chuck Collras. The contest promoters could always count on Chuck showing up to compete which was quite important if you wanted to promote an event with more than five contenders.
And Chuck always appeared on stage in tip-top condition.
And Chuck was very short.
And for some unknown reason the name "REG LEWIS" pops into my head while I'm typing this. He and his beautiful wife also conpeted back then. Maybe one of you wise GetBiggers can help in this regards. (Sheri Lewis?

?)
That photo above seems to have been taken at Joe Gold's second location but where the hell was Draper and a few others who appear to be missing?
