Need more info to help with the value...
Do you have a model number (500, 515, 525 etc.). Should be a small brass tag riveted to the mast on the passenger side.
Do you have the complete assembly (Winch, Mast and Booms)?
Is there a service body? What style, Platform or Chariot?
Any accessories come with it (Beacon Ray Light, Axle cradle, Dolly Wheels, Ground Anchors, Scotch Blocks, Snatch Blocks etc.)?
What size truck are you putting it on?
How about a picture...
