UPDATE:
Hello
Update on this lads....
This is something that means quite a lot to me
Many hours of research, many emails back and forth to folks involved, many pigeon english emails with a Japanese sculptor, many incorrect purchases of what I believed the bottles to be and many cut fingers and splitners to make my
prototype version, made just before CE, shown here:
With help from the sculptor and a lovely Japanese lady named Akiko who I used to work with

I've managed to track down the exact thing used way back in 76 to recreate the bottles used on the Death Star surface and what a lot have believed for a long time were also then used on the back of the 2 TKs outside the Death Star as the Falcon gets sucked in
Here the guys are
Cleaned up in photoshop
This image shows the bottle tops are flat with some nipple on top
This toy made many moons ago shows what the maker thought the bottles should look like (this was based on what he was told BTW

)
When most saw those bottles, it was dismissed as being inaccurate due to the hose and fastening to the chest.......
However a few years ago a chap on the RPF thought they might be bottles used on the Death Star surface. Then there was a SW exhibition in London. In there they had a few meters of the Death Star surface and these turret guns. I saw these bottles (before the link was made) and yes, they're about the correct size

Close up, here
Now then....
Does this look familiar to you
I then went through everything to try and recreate the shapes seen. this is what I've come up with so far
With a clue from the scupltor I then managed to nail it down further with the help of this pattern here (thanks to Alex Howard for the reminder on this pattern)
I'm pretty happy with myself after some 5+ years of fiddling with this.
All I need to do now, is take my time, create the rest of the detail and vac form a new bottom
This is all I have on that so far. The sculptor was told those lower parts were just made up
However, I doubt that and they MUST have been used elsewhere in the film.
So can I ask if anyone wants to kindly sit down and watch ANH 100 times in slow mo to find the lower bit, feel free.
