Scarf man--what argument?
I don't agree that everything is subjective. In cases where there is evidence, two people can think they see different things, but only one of them at most is correct. The whole point of threads like this is to figure out what is correct by examining the evidence--which implies the possibility of arriving at an objective conclusion.
With regard to the cross-section of Chris' particular split pin (I'll adopt Keith's term as it is more technically accurate, although 'cotter' is more common in US usage), below I have circled the areas where a rapid change to a flat plane is visible.
If the 'wire' on the prop can be shown to have this sort of shape, then that's definitely evidence that the 'ring' piece may have been used.
If the 'wire' on the prop is indeed round as I think (so far
), that is not evidence against the use of the 'ring' piece, it just leaves us where we started, with a hunch, a possibility, and not really any evidence.
It is possible that some boosters had makeshift pins made of regular wire, but even if we found one I don't know how much weight that should give to the idea that the 'ring' was used.
Just to be extra-clear--I don't have a 'position' about the ring piece, I think it may or may not be there. I think there's a certain logic to the idea of it having been used, no question.
About what to call it--the confusing thing is, some have argued that the ring piece itself is technically the actual 'booster'. I'm not sure this is correct, as the both pieces are required for the 'boosting' (recoil enhancement on the gun) to occur.
In terms of its function, maybe it should be called a 'booster baffle'.

My research found that the ring of holes is called the Bearing and the other part is called the Booster.
In the chronicles pic, I can see a flat edge but since the image isn't that great, it could be anything. Also, maybe the cotter pin was flipped around so the round head area was on the other side of the Bearing. This would make the wire longer to wrap around.
Anyway, like Serafino said, we will never know for sure unless we get new evidence.

Here's my .02 cents.
When I made that all-real-parts Obi Saber for kurtyboy, we decided to keep this extra part attached to the booster and use it under the clamp.
With the part screwed all the way down, it was impossible to run the wire through the holes in the clamp because the round flange with the ring of holes is right where the clamp holes are.
I was not using a flat cotter pin, but 6D nails as they size up nicely. Unscrewing the extra part slightly reveled the lower hole, but even then I had to file the nail flat on one side to get it in the hole.
It was my belief that the purpose of the wire was to keep the clamp from slipping down as the saber is worn on the belt. On the booster, the pins are exactly opposite eachother, and on the clamp the holes are also opposite eachother.
If you ran the flat pin down the ring of holes toward the handwheel, bent it 90 degrees, pushed it out the lower hole, and bent it in a curve between the booster fins then it would look like the photos. However, this would not keep the clamp from sliding toward the grenade, and it's next to impossible given how tight the clamp is.
If you ran the pin out the holes toward the handwheel, out of the clamp between the booster fins, bent it 90 degrees between the booster fins and back up toward the clamp ind inserted it in the clamp holes (where the pins started) you would have the same effect and keep the clamp from sliding down when belt worn.

Also, I have seen/used cotter pins that were made from flat wire, and also ones made from wire that was flat on the insides and round on the top making a 'round' wire when both halves are together.
It would not surprise me at all to see that we are only seeing the top round side of the wire. Our brains tell us the wire must be round all the way because most wire is, we see a curve, and the clamp holes are round.

Is this a LFL image?
I know the part Seo's referring to.
I know it's been discussed here before that these cotter pins could possibly be what is coming out of the clamp holes. The ring itself is too thick and interferes if it's screwed down all the way.

I think it's possible the wire is flat on the back.
The highlight on the edge doesn't look like it's in the right spot if the wire was full round.
Upper right corner in this pic is the real booster pin at nearly the same orientation as I see it in the prop pic. I think it's a strong possibility.
BTW - The booster pic is not mine. It's just one of the pics in my Obi-Wan saber files. I don't remember where it came from. I don't have a real booster - yet.
PS - If the booster bearing was used here then it's unlikely another was used to attach the emitter. Howard will be upset after cutting his up.

Looking right on to me.I think that's his personal booster.
Serafino, this is what I see:

When I look at those pictures I notice thet the wire does not come out from the center of the hole.
It seems someone cut a channe from the hole to the edge of the clamp. That would make sense in my opinion since it would be next to impossible to thread the cotter pin throught the hole in the clamp and through the bearing. the clamp (to me ) appears to have been slid on from the grenade side (or the booster/bearing assembly slid into the clamp from the bottom) with the cotter pin already in place.
If someone can get me some dimensions of this bearing I could machine one and test it out. I have a booster already.

I made this a while back and it's an average of 7 boosters:

Ok making this part the way it is exactly would be absolutely pointless. If we knew for sure that it was in there, and I mean with 100% certainty, maybe it would make a little bit of sense, just for coolness sake.
maybe making it with an extension so that it would reach and attach itself to the grenade would be better.
Actually, come to think of it, if this piece were attached to the booster just the way it is shown above, it would make it extremely hard to then attach the forward part of the saber to it (unless there is a hole on the top which isn't visible, or if a hole were drilled into it and then maybe tapped for the threaded rod).
This would be a pretty simple part to make, but to what purpose ?
