It seems like Sentra Surya Ekajaya (SSE) rebranded, or maybe licensed, KamAZ-4350 "Mustang" as P5 Boma. It's the 4 wheeled version rather than the 6 wheeled version KamAZ-5350.
The TKDN is unknown. It's possible that it became the basis for early version of P2 Tiger before using Texelis drivetrain?
