Raceface crank timeline help req

[Scrat]

Is anyone a turbine crank expert?

When did the first IB crankset go into production? what sort of numbers were made?
Turbine LP went on sale in 93, billet at first then from Forged in 94.

Cheers in advance

Just thought I'd give this unanswered 15 year old thread a nudge.
Anyone have any clarity on the timeline for RaceFace products?

Next post might not be until November 2039...

I have a set of Turbines which are marked RaceFace only, no 'forged', so I assume these are early?
