It should have some value. I don't know how much. I suggest you put in in the parts for sale at a low price plus shipping and see what happens. If no action there then put it on ebay or put it in the free stuff here in the proper forum. The deal is that delivery costs for items in free stuff are generally paid by the recipient.

BTW: I don't know if you notified the vendor of the part(s) that he sent you the wrong but if you did then he should have made you whole. That is, send the right parts at his expense or paid you your money back plus shipping both ways. If I were your vendor on that transaction, that's what I would have done.
BTW2: If all else fails, consider the fact that you have a lot of water over there. Run a stout line through the ring gear and use it as a boat anchor. Use the pinion as a fish stunner.
BTW3: If you had any hills there, I would advise using it as do folk living over here in Tennessee. They run a stout line through it and throw it out when descending steep mountain sides. Helps prevent the brakes from becoming overheated. Does too! And, it don't hurt none at all like it does when sticking out an unshod foot in order to realize the same result. Sure don't (so I'm told).

Grin.
