That thickness on the SSE side is a bit of an optical illusion. It's the cable guide on the Cinelli lug, actually set back a bit from the lip of the shell. I'm fairly confident there isn't a major structural issue as the frame has a serial number (wouldn't get one right if it didn't pass QC?) and no signs of any damage or craziness done to it.
