3 main things to look for to find yourself the correct type:
1.Strap attachment point-this should be help on by a single rounded rivet, some incorrect styles have a flattened piece the curves into a slot, also look closely at the part that the strap fits through that also varies in thickness and shape from manufacturer to manufacturer .
2.Lens shape -the lens she has is a smooth curve, incorrect styles have flat lens or angled lens with sort of a corner at the edge of the eye like this one

3.Color- I know it goes without saying but black padding, black strap, chrome accents and see through yellow lenses, you will stumble across some with brown padding, or mirrored lenses more easily.
Here is the closest I've found
http://www.ebay.com/itm/191496963952 as for the magnifying lenses they are very common and cheap to come by i bought mine at harbor freight, most brands offer the exact same configuration so it's hard to choose wrong
http://www.ebay.com/itm/401080215992 The magnifying lenses will need some modification to get them just right and the trailer doesn't have a clear enough shot to tell exactly how and where they are attached and modified. For mine I just drilled a 1/16th hole at what felt like a natural spot on the rim of the goggles going by the two scenes we see these in, and added a spacer ( the lenses will hang loose with out spacer after the clamp is removed) and tightened it on.
I am positive there will have to be more changes to this in the future when more information comes in but this should get you started.
On a side note I love these goggles, I mean for all of $20 and 10 minutes of work you can have a screen accurate replica and the goggles themselves are very comfortable over your eyes or on your head, much more so that ecto goggles.
Oh by the way If you are interested in her main glasses
https://originalstradingco.com/product/ ... 3-spectre/, little pricey at almost $90 and far too few made with the 150 production run but at least we know what they are and who they are from.
So now all we have to find is the finial fight glasses, the other goggles (feet kicked up) and the goggles/head gear she has flipped up in the lab...... this gal has a lot of great gear to keep up with, but hey at least it is way easier than searching for stuff from a 30 year old film that used some equipment that was already 20 years old when they used it, right?
