So, back in my "gen" days, it was well discussed that the Tudor Ranger was a fantasy watch. That any that were for sale were ALL contrived, no matter what was said by whom. Anyway, without iron clad proof, I would suspect any Ranger, period. Similarly, I would suspect any 5500 Explorer as well. Just too many reps out there these days.
Let me clarify my statement, it was the RED Rangers that are the "fantasy watches" the ebay one may very well be genuine, as white Rangers were real. Only way to tell is to have it verified by Rolex.
