Is anyone able to shed any light on the T700 mainshaft differences?

One has black writing, one has white writing (no big deal) but I also have another one with black writing but it doesn't have the notches in the top for flybar clearance when at maximum tilt.
It's from what I assume to be a recent kit because the front tail case has the hole for pinning the boom.

Which mainshaft is the current revision? (HN7010, HN7010-1, or HN7010T-1) & it that white or black writing, with or without flybar clearance notches.

The one without the notch should be the current version. Both works.

I think those with notch came with the main shaft shims, while the newer ones have the shims sold seperately.

#61 on the 700N list and Proud of it.

Thanks.

I wonder why they had the notch in the first place?
It doesn't look like the flybar contacts the top of the shaft.

I thought the two notches line up where the two 4mm bolts go through the headblock?

The mainshaft with notches sometimes allows the flybar to deflect enough to allow the paddles to hit the boom. Not a problem when the blades are at speed, but definitely a problem when the blades are coming to a stop during blade-stop autos, for example.

So now the problem that arises is how do we ensure we are buying the revised version when ordering online?
