1944.... It was still listed as.............Cochran & Palm
1948............................................ Nine Twenty Four BilliardsClub (924 Market St. ?) w/ Welker Jr.

All this info is from S.F. City Directory ( Ancestry.com)

*** I was looking into the 924 Club chips. They are listed as being from......
924 6Th St. San Francisco...................... TGT
Priest River, ID................ TGT
924 6TH St. Sacramento......................... Richard Edward Sttaeffler's Memorial Site
924 6TH St. Sacramento........................ The MoGH
I believe these chips are probably from 924 Market St since they already had a business at a 924 address.
ANY THOUGHT??? your input is appreciated
