Help with a B400 from 1980, How much is this cue worth in 90%+ condition

VIKING B400 model, with 2 original shafts that are still 13mm. The cue is all original and has a few bumps on the bumper area otherwise it is in perfect condition. Both shafts roll flat and true? What do you think the market would put the value at and how many of these do you think are still around, because these were so expensive for the time and considered a production cue, I don't think many were sold when new?

Any info would help, thanks, sorry no pictures, because my camera is down,
