Sigurdd50

I am going to go look at this Schwinn Voyageur SP (hopefully)... but wonder if any one can peg a date on it before I go. Component desc (which may not be orig) incl:
Sugino AD cranks
Shimano Deore road group drive train
Dia Compe brakes
Key desc: Frame is light blue with dark blue head tube

I couldnt find any similar pics on google image
any ideas?
