Whats a 30yr old Warn 8000 winch worth?

[fmlewis]

I looking to find out opinions of what an old Warn 8000 is worth? I don't know the exact model number but it looks like an 8274. Where is the model number located?

It is in good working condition. It also has the in cab cable pull spool release also.

Let me know you think something like this would be worth.
