The Gazelles I used to instruct on (the RAF HT2) had oil lubricated lead/lag hinges (single blade pin), pitch change hinges and flapping hinges.
In my book that makes it a fully articulated rotor head.
The drag dampers are called "pseudo" dampers and are elastomeric in construction (bonded strips of sandwiched steel/rubber), rather than of the more conventional hydraulic type.
Perhaps it's the latter causing confusion?
