·Seriously, here's a first generation 1956 that was on ebay recently and that seems 100% original, even the crystal ! (different dial from your last photo, longer indexes and no circle around the date), you can see that the hands are "second" generation type but they are made for this dial (look at the end matching the markers. Sala's got these hands on the first generation aswell page 351. So I stick to all kind of mixing in the (long) transition period.
Saw this one also and was about to buy it for a projet with the later dial.
Both options are possible and acceptable 😀
