can anyone id this sofa?

fabe bought this sofa back in 2000 and now needs to get a new slipcover but he can't identify which model it is.

"we've been to a variety of websites and the ikea store, but no one has been able to identify which model it is. and because it is an older model that wasn't continued, we're wondering if anyone has a new slipcover (bemz and eBay seemingly did not)."

here are the dimensions:
cushion depth --> 27 inches
arm depth --> 38+ inches
height --> ~26 inches
length --> ~88 inches

it looks somewhat like the ektorp but the dimensions are off. anyone?
