The seller does have both the wireless and wired remote for the winch... i know its easy to get replacements, but i assume these were locked either inside the landy or in the house so chances are were not stolen at the same time.
That said, he is also operating out of a container...!
thanks for the ebay link, thats no the one!, the winch was one of those unbranded ones off Ebay! with the box of contactors mounted on top of the winch
