Hi Gordon,
yes I am passionate about Patek Philippe's history and I think I will try to bring this research work to a next level, even if I don't know how exactly right now.
I have updated the post with 5 more retailers (56 in total now): Albonico, Boucheron, Brinkmann, Horovitz & Keltz-Bloch.
As for your question, I'm unable to answer it: I think I would need to be more “inside” the Patek Philippe manufacture and history department to be able to give an answer.
Best, Emmanuel
