Corydora True ID

[Vancouver_98683]

Got this today from an owner that no longer was able to take care of. It's a pretty big one 4" in size. It's monsterous compared to my 2.5 albinos. I searched the net and came across corysrus.com for referencing. But there are so many of them which looks similar. My best guess is Corydoras brevirostris. Only difference is the vertical line over the eyes and mine is a dark face and no line.

Looking for the cory experts here. Would anyone know right off the bat? ID'ing this would be greatly appreciated. Thanks for reading!

Anyone? Correction on his/her size. Finally got close to the glass for measuring. 3.5" is true size and fatty is broad. From the gills back it's identical to brevirostris, but have noticed if a line or spot differs, then it may be something else, i.e. C classifications. I'm new to Corys.
