Agusta was the lead partner from the start.
Bell was the secondary partner for the first 54 aircraft.
Westland has been the secondary partner ever since.
Seeing as 93% of the aircraft built so far don't have the Bell moniker nor Bell support, it's a stretch to call it a Bell product at this stage of the game.
So far as I'm aware, Bell did no assembly in N. America at all, with the AW plant in N. Philadelphia doing all the N. American work.
I do believe Era has operated the 139 with a hook in Alaska.
