The International Labor Defense holiday roster in the December 29, 1925 Daily Worker lists this prisoner, printed as Wm. Longstreth, at San Quentin California. Its printed identifier is 39346; 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
