Biography
Roy A. Carter was an IWW member from Portola. Roy A. Carter received a four-year prison sentence, which he served in San Quentin from October 29, 1923, until his term expired.
The International Labor Defense holiday roster in the December 29, 1925 Daily Worker lists this prisoner, printed as Roy Carter, at San Quentin California. Its printed identifier is 38533; this is a prison number or mailing designation, not a year or a custody date. This documents confinement at the roster’s reporting time, without establishing an admission, transfer, release, new conviction or complete duration. Existing independently sourced custody chronology remains separate. Source: https://www.marxists.org/history/usa/pubs/dailyworker/1925/1925-ny/v02b-n297-NYE-dec-29-1925-DW-LOC.pdf#page=5
The May 1927 Labor Defender explicitly lists Roy A. Carter among prisoners actually released, giving January 29, 1927. This contemporary completed-release report corrects the earlier missing or conflicting endpoint. It does not establish complete continuous custody or turn an imposed term into actual time served.

The February 26, 1924 Daily Worker political-prisoner roster individually prints Roy Carter with historical prisoner number 38533. Its continued Walla Walla heading appears to run into California prisoners, while this individual’s existing record documents San Quentin. The printed identifier is transcribed; no transfer to Washington or institution change is inferred from that heading. This is a contemporary institutional identifier, not a federal BOP register number. No admission or release date, individual sentence length, actual duration, organizational membership or present status is inferred.
