I recently acquired a trench style watch. I love the style and feel of it so I had it serviced. The watchmaker informed me that the setting lever was worn and he had no access to parts. I'm trying to identify the movement. I have found pictures a Marconi Lever (attached) that look the same, but it also is very near an A.Michel caliber 220. I believe the movement is 13ligne, but I don't have an accurate measurement. There is no other markings other than those visible in the photos. Any...
