Batavus - Mystery Model

Picked up this very-well-preserved Batavus a couple weeks ago and need the VintageRacingBicycle community to help me figure out what model it is. Mostly Shimano 600 (circa 1985) components with Campagnolo Nuovo Record rear derailleur and seatpost (SR LaPrade in photos). 

Beautiful paint job and fine frame finish work. Campagnolo dropouts, Columbus (aero-style) fork, wrap-around seat stays, chrome chain stay - more pictures HERE.

Thanks!
