[2] Los Angeles sports columnist Max Stiles knew Robinson during this era and stayed friends with his brothers Jake and Saul.

In 1935 he was described as the operator of a "newsstand and cigar counter in the cafe at Universal City where he sells everything from soap bubble pipes to Prince Matchabelli perfume.

[6] Around the same time, Robinson was apparently partners with Eddy Neales and Milton "Farmer" Page in the Clover Club, "a high-rolling Hollywood nightclub and casino just west of the Chateau Marmont above the Sunset Strip".

[7] When Mickey Cohen wanted in the action and the partners refused, he roughed up Neales, raided the club multiple times and carried off the cash on hand, and even robbed patron Betty Grable of a diamond necklace she was wearing.

[9] In 1940, a county grand jury was told that "George Contreras of the Sheriff's vice squad was interested in 2000 marble and slot machines" and Robinson was one of the witnesses summoned to testify.

[10] In 1942 the Long Beach Independent threw a fit in editorial form when Robinson tried to expand his slot-machine racket there, with the assistance of lawyer Fred Howser and "Mrs. Martha W. Campbell, president of the Women's Better Government League".

Mr. Robinson, thereupon went into the county, where he was said to have established good relations with some law enforcement official called 'Cactus Eye' and has been doing quite well since that time and, being ambitious, is trying to set up in Long Beach.

"[11] In the 1940s, Robinson was the head of the Associated Operators of Los Angeles County (AOLOC), a trade group representing owners of slot machines and other coin-operated games.

[12] In 1955, when unidentified gunmen shot up the home of "Bingo King" Max Kleiger in Pacific Palisades, the Los Angeles Mirror reported, "The beach front gambler's name popped up in Kefauver committee testimony here a few years ago in connection with an alleged plot to recall then Mayor Bowron so that open gambling could run in the city.

The five people in the meeting were reportedly Bob Gans, Max Kleiger, Jimmy "the Eel" Utley, Curly Robinson, and Sammy Rummel.
