As I dont see it mentioned in the VERY informative first post, the different supersport/lightning troggers deserve some mention:

-Early supersports, both Mk1 and Mk2, shared the simple plastic single stage trigger blade of the Meteor Mk5.

-At some time the plastic trigger blade was changed to a machined and anodized aluminium version, which was spring loaded and gives the impression of a two-stage trigger.

-Later, the machined and anodized blade was changed to a cast version, which retains the pseudo-two-stage function.

-the steel parts of the trigger mechanism was at some time changed from hardened steel stampings to cast or maybe sintered parts.


Can anyone place approximate dates for the changes mentioned above?
