Thank you Prez, I googled 2170 Y and I found more images http://www.manifestcreations.net/goods/20140810083752-2309.html
Not that at this point it is of capital importance, but for the sake of completeness - although you are probably right - I confess I am not 100% (only 90% ) convinced that it's the Barrie last. I mean, yes the welt is surely larger but the upper looks just the same of the 2160 Aberdeen, just put on a differently shaped welt. Shouldn't the last be something concerning the shape of the upper (so basically the inner part) and not of the sole/welt?
Those shoes are either barrie last or might even be trublance. It is not at all the model 2160 shoe.
