Toothless Nuovo Gran Sport?

I've just (finally) taken possession of the long awaited Gazelle Champion Mondial cross bike. Just a quick question : the rear der. is Nuovo Gran Sport, bottom jockey wheel has the well-known pointed teeth look, but it's the top one that puzzles me; completely smooth! I can imagine the teeth being worn and pointed, but no teeth at all??? Surely there should be something left UNLESS it's supposed to look like that (which I doubt). Ideas?

The Gran Sport derailleur, the one before the Nuovo Grand Sport, had toothless jockey wheels. At some point in the last 30-40 years someone probably changed the wheel on yours.

In fact, metal wheels with tiny ball bearings, at least circa 1960.

The Huret Allvit used the same style jockeys (though on a much less functional piece of hardware).

Well, in that case, you either have a worthless piece of worn out plastic, or an amazingly valuable collector's item. I think the first case is much more likely.
