Historical Notes
Early Phoenix Gold and M-Series Emergence
Archived Phoenix FAQ material lists M-series output tables and identifies a 1992-1995 production window, while secondary history notes describe the broader late-1980s to early-1990s brand ramp.
Outlaw and Bandit Relationship
Registry-sourced descriptions identify Outlaw as a combined M50 + M100 architecture and Bandit as an M50 Rev. B cosmetic companion model. Claimed serial ranges and total counts are presented as non-official estimates.
