It's a bit tough to tell when it comes to the airsoft bases they used since there's clones and such, but either way the Marushin/Tercel and gas HFC/Bell appear to be the only likely candidates. It's difficult to tell without better photos, but it looks possible that the Wired blaster is the Marushin, and the promo/disney variations are the metal HFC (the one without mauser markings).
The screw between the gripframe and the trigger would be an easy way to tell which was used for the Wired blaster, since the Tercel has a fake screw there, but the two known photos available of this blaster so far aren't clear enough to tell.
The disney blaster appears to be the same general build as most of the promo photos and artwork that's out so far, since the Marushin is the only one that doesn't have a square notch on the bottom of the magazine. And I'm not sure if there's a short mag for the Tercel or not.
The easiest way to tell whether it's the HFC or Bell would be the set-screw that's in the top-front of the bolt. If that area is visible and can be photographed from the display that would tell us which they used..for the display blasters anyways. Presumably the promo blasters would be the same though.
There appears to be two versions of the gas HFC, both have the same general details, except one has mauser markings and the other has mold ejector marks on the hammer. I can't seem to find much on the marked version, but since the artwork has those round marks on the hammer it seems like a good chance the one without mauser markings was used for the props seen in the promo photos and possibly the disney blaster.
There also appears to be two different mystery disks looking between the promo and the disney blasters.
The real mystery though seems to be the Flash Hider used on all these blasters! Custom maybe?
