Managed to buy this 1938 Seitz tool complete from a retried French watchmaker, who probably purchased it used or inherited it. It wasn't cheap but such a rare and complete tool couldn't be. Doesn't have the micrometric screw from the newer version, and it takes 3mm stumps instead of 4mm like the new ones but I can replace jewels in rubbed in settings with it and such tools haven't been made in a very, very long time. A separate set for that would still be really expensive anyways, and from the US, which makes is much worse.
The pivot breaker works well too. One down.
