Now as to why I posted all this stuff: to compare it to Ross's shell. Ross's shell is particularly interesting. If you have been following, you would notice that the GB1 Heros did NOT have the N-Filter cast onto the shell, but every other incarceration of the shells used in both films as well as the USF show do.
BUT, all these other shells used in production had at least the booster tube or part of the booster tube cast into the shell as well. Then the GB1 stunts had tons of extra material added around the molded in tubing, as does the USF shell. If Ross's shell was a 2nd Generation cast from a GB1 original production mold, there would be several differences then what are currently on the shells he offers.
First, the N-Filter would not be on there. Plan and simple. And if it was cast from a "stunt mold" it would also have everything else on it, such as the booster tube + frame, injector tubes, beam line, filler tube, PPD, HGA, and Ion Arm. It doesn't and considering all the small imperfections on the shell already, then there would be even more from the clean up of removing those things from the master to get the shell where it is now.
Second, the EDA discs do not have the "nipples" on them.
The discs are there, but the "nipples" are not. As you can see from this GB1 Retrofitted Hero used in GB2, they can easily be seen.
There's also a bulge on the sync generator that is not on any other production shell ever seen.
Lastly, there's a ton of the imperfections that are on the hero packs in GB1 that are non-existent on Ross's shell. The ribs have no wood grain on them, for one.

There's also penny nail's that they didn't do a great job filling in on the master that shows up on both the hero and semi-hero packs. Here you can see it on the bottom powercell rib of this semi-hero shell:
It can even be seen on the OMNI pack:
Non-existent on Ross's shell:
Production shell? As far as I'm concerned, no. Does it have some connection to the hero packs? Well, yes. As Videobob and Ross have both pointed out, the N-Filter on this shell is the same exact one that is on the Hero on display at Sony's Lobby.
Here's the story I was informed of about this shell. Everyone sit down and get cozy, its story time.
From what I understand, at some point after GB2, the hero pack that was on display at NYC Planet Hollywood and later in Sony's Lobby was removed from display and taken apart. During this time, someone took measurements from the shell, and reconstructed a new master from the measurements taken directly from the shell. During the molding process, they decided they'd pull the N-Filter off the Sony Hero and placed it on this new master for the casting, instead of making a new one. After it was molded, the N-Filter was reattached to the Sony Hero as it was reassembled and returned to display.
How true is that story? You got me. There tends to be a lot of "whisper down the alley" in the prop builders communities. But does it make sense? It would explain this shell and why it has some things, but not others and does not fit into the obvious lineage of molds made for the movies and USF. It would also fit into other stories I have heard over the years with the handling of the Sony Hero Pack, which I am not sure if I am allowed to discuss publicly.
Anyway, that's how I came to my conclusion about Ross's shell. Production piece? Probably not. Some ties to the screen used props in some small way? Yes. The N-Filter is proof of that.
