I agree that the grips are by Joe Blackford who predated Farrant in making grips along with Walter Stark.

Walter Rickell July – August, 1973 Gun Sport magazine, “The Combat Revolver Grip”
The whole thing started around 1936 with Walter Stark, a Los Angeles police officer who was on the police pistol team. While firing his revolver standard NRA course one day, he found that most of these revolvers, which were converted to a short single-action, had unsatisfactory factory grips, so he started to experiment.
... the first models were equipped with finger grooves to facilitate the positioning problem, but still left the natural position of the hand to be overcome. Here Jo Blackford, a student of Stark’s, came up with the idea in 1953 to cut a section from the lower front portion of the revolver grip frame, which relieved the little finger and left the hand in natural position, eliminating any tension on the forearm.
From this grew the combat grips made today by Stark’s students, Jo Blackford, E. M. “Fuzzy” Farrant, John Hurst and Guy Hogue.

This may be the Joe Blackford we want to know about:
Josiah C. Blackford retired with pension from the LAPD on June 1, 1974. Here are minutes of the pension board acting in 2005 on his distribution after his death a few months earlier.
LAFPP
Josiah C. Blackford -- Police Service Retired: 06-01-74 -- Died: 09-22-04
He died in Sequim, WA on Sep 22, 2004. SSDI records record his DOB as Oct 19, 1922. We know from the two available census records in which he appears as a juvenile that he was born in California.
If he was a career guy with LAPD, which the pension award indicates, he could have joined the department in the mid- to late 1940s. That's exactly the time frame when he would have run into Stark, Farrant and the others. There are service records showing that he was in the USMC from January 1942 to January 1946, so could not have joined the department before his discharge. There are also records showing him as MC Reserve from 1956-59.
An interesting aspect is that his father, Clyde Blackford, is identified in the census of 1930 and 1940 as a carpenter -- in 1940, a finish carpenter. Joe could have learned some basic woodworking familiarity at home before running into guys like Stark and Farrant in his own work environment.
