I really think yours is a better sample of those 4240 calendars
I've seen many many of them and my summary would be, yours wabi is very tolerable and pleasant.
Beeing initially cautious was mainly because of the index configuration I haven't seen before and the not so good pictures from your side.
But I found a dial very similar - what would rise the conclusion yours is in deed original.
Here is the reference picture (source: Drouot Richelieu Auction, Paris) for your dial configuration:

I would like to add your movement V&C cal P485 is also one of the more attractive and desireable ones (if you could choose between some of the movements): Swan neck micro regulator / shock proof / full inscription / little to no wear visible on the bridges / original crown.
Yours for comparison (below).

You should not be unhappy with yours. My estimation would be significantly higher than that given a decade ago by Drouot.
