Market for good disc mower conditioner

Hi folks, 

I know the typical answer for this question is "go to tractorhouse and see the auction or sold results".  But there are so few comparibles on this...

 

John Deere 1460 Mower Conditioner.  1991 or so year.  Was one of the first JD MowerConditioners out.  Basically a Kuhn painted green.  Rubber rolls.

Hasn't had many acres over it through life.  Always shedded, taken care of, well maintained.  All original.  Currently washed and waxed, new blades.  Still has orginal curtains that are in good shape.

  Besides grandpa, I'm the only owner.  

What's this thing worth?  Especially now, in season?  Sort of one of those "barn finds" that I'd like to have, but I'm in the market for a bigger mower now.
