To be fair to AW - They have also produced a market leader in the guise of the 139 and were the first rotary OEM to pursue the 'family' of types?
Uhm, lets not forget the UH-1B (and variants), UH-1H (and variants), UH-1N (and variants), UH-1Y, Bell 204, Bell 205, Bell 212, Bell 412, Bell 214B and Bell 214ST.
Bell very successfully built an enormous selection of military and commercial helicopters from one model, being mass produced by many other manufacturers, including Agusta.
I have never understood why Bell sold their share of the 139, which I would agree is one of the best helicopters ever produced.
