Just saw that in a 2012 workstation thread and was like "Umm ... it's a Galant .. but not quite" ... The corner piece looks a little more symmetric than current US Galant -- do both left and right sides have the same depth (a.k.a. width)?
The left side has a depth of 31.5", and the right is 23.5". I've got five more Ikea desks besides this one. I'll take a few pics of those, and post as well.
