They've been there since ANH. It might be hard to discern, but the grub screw is just seen poking out on camera left. The nipple is in a different orientation in relation to that grub as well. I'm sure there's a color version of this or a similar shot somewhere, but I can't find it.

A lot of this was covered some years back on the V2 proper thread that
teecrooz linked to, but at 100+ pages of rampant speculation that lead to few discoveries, I will be the first to admit it's a lot to go through.
Within that thread, I forget who it was that did it, but someone pulled up the call sheets and shooting schedule for the day of the cut 'sandstorm opening sequence', where the photograph of the Graflex oversight was noticed, and they compared the timetables. It was figured that the timeframe for the V2, swapped in and gussed up, quite literally happened over a lunch break.
While Brandon leaves open the possibility that there may have been a different emitter with a nipple and emitter that moved independently, he's almost certain that it's this V2 in his possession for much of production on ANH. There were very few multiples for the film series, let alone the first. The details on the V2 he insists are intentional and that it was almost as-it-is now since production of the first film.
Thanks so much for this. I did go over this thread, (believe it or not) and thought I'd managed to take in everything from it that I needed. Obviously not!
I'll put aside some time to go through it again from start to finish for sure. I realise I'm a little late to the party with the V2, and a lot of hard work has been done already by others. I'm determined to do as much as I can to do my own homework though, and not to stand on the shoulders of others too much.
This is interesting then, as I'm 100% certain that there are shots on the Death Star in ANH where the blade is spinning, but the emitter isn't. I was watching it again today frame by frame. this sequence in particular stands out:
The markings on the emitter face make it very clear that the emitter isn't spinning, so can't be fixed to the bade/internal rod.
Maybe the set screws we're talking about here could be to secure the bearing (as
thd9791 suggested)?? There does appear to be something sitting just bellow the surface, under the nipple, to my eyes. Perhaps its the bearing? Maybe the nipple doesn't go much deeper than the surface of the emitter face?
Definitely something there. Maybe another step in the nipple itself, but I'm inclined to believe it's something separate. It just looks to have slightly different qualities to me and even a more bronze-like colour than the aluminium? Maybe I'm seeing more than is there from such a grainy image?
I am definitely taking all this on board and will come back with a proper update soon that pieces all this together.
I made some progress on the mystery pommel mark earlier today too, but I'm not quite ready to post this. There have been a few discussions going on behind the scenes regarding the sharing of information. Without going in to too much detail, I'm going to need to strike a balance between the valuable discussion that is needed as part of the development process, and the sharing of of information that can (and has been) used by people who are too lazy and unscrupulous to do their own homework.
This puts me in a strange position, as I want to be as thorough and as open as possible, and LOVE discussing every little detail, but I will need to reign things in a little and keep some specific details a little closer to my chest for the time being.
I will hopefully manage to strike a balance in the way that I present my findings going forward.
