I had one that I restored a few months ago. I bought it for $50 and traded it even for a WARN XD9000i
The winch after the resto;
Its a really stout winch but the Belleview does not have a "reverse out" function. It free spools with a brake. The Belleview was cable controlled from the cab and came from the factory on older Scouts, Jeeps and Rovers.
The Belleview was the predecessor to the 8274. The one pictured above is not worth 300, I would give 25 for it, its only worth parts in the shape its in. Also worth noting, you can rebuild a Belleview with off the shelf parts out of a Granger catalog. Restored and in perfect condition with the cable controls(mine had those as well) its worth at least $500.
It has a oil filled case and it uses straight 30wt oil. I added a drain plug to mine for easier servicing.
I traded mine for the XD9000 to a guy that was restoring a 74 CJ-5 and needed a correct era winch on it.
