Olivetti 290 SP

The Olivetti 290 SP is a 286 computer that was released in the early 90's. Just like how the Olivetti 290-30 appears to be a variant of the M290-30, the 290 SP appears to be a variant of the PC PRO 290 SP. Is the 290 SP simply a PC PRO 290 SP that got part of its name erased? Apparently not, as there seems to be another picture of a 290 SP on the web. It uses the BU case design (probably BU 290 S-XX).
