9 or 10 inches across does sound about right for the small size, as the medium (in the middle in that video) is 12 inches across. Maybe the bag just comes across bigger in videos than it does in person? I
have seen the small size IRL before (a friend owns one), and I recall it being quite a bit smaller than the medium Trigger... If the bag you received has slouched over time as well, that might also affect how it comes across in person, vs the boxy new bags in the video.
Unfortunately, I don't think that's an indicator of the older vs newer Triggers... My 2009 version also still had the metal Botkier logo plate, although that was in the older style logo plate (with rounded sides and the studs/screws on the sides of the logo plate), as also seen in the 2nd video I linked. This logo plate was also still used on other Botkiers, in 2010 and probably up until the logo re-design some time in 2011 (as mentioned by Monica in the 1st video I linked). The 2011 re-designed Trigger had the new logo (with different font type), and the logo plate was rectangular in shape from then onwards.
I don't know when they stopped using the logo plates on bags after 2011, but as far as I can recall, all Triggers that followed the original design (with the front and back magnetic compartments, trigger clip on the back, etc) had the logo plate. The 2011 re-design was the last time I recall Botkier releasing the Trigger in this original form in retail stores (at least online), though I do recall seeing a Trigger once in an outlet store in 2014 or so that followed the original design (I think it had the metal logo plate too, though I don't know this for sure -- also not sure if it was "made for outlet" or something, as I never saw that bag in retail stores online).
Otherwise, if a Trigger doesn't have the metal plate, from what I know, I think it was most likely a bag from the 2013 "re-release" onwards -- but honestly, the modifications from 2013 "re-design" were so drastic that I don't really regard it as the true Trigger! There's a pic of it here, on Purse Blog:

As for other ways to differentiate the older old-school Triggers from the newer ones like from 2009 to 2011, maybe the interiors might be more of a distinguishing factor? My 2009 and 2011 Triggers had the fairly standard handbag interior of a back zip pocket, and front panel slip pockets along with Botkier's long chain keyleash (I don't have pics of the exact interiors handy, but they're basically like
these pics of the interior of another Botkier I had from the same timeframe). On the other hand, I've seen old-school Triggers (not sure from which years) that have simpler interiors, or that have leather panel lined slip pockets instead.
Glad you'll be able to return the small Trigger you received, and good luck with your search! It might stlll be tough, but I hope you'll find the one for you
