Other info: Re-posting Liz's Factory S "200" variant (with 16J) from previous forum threads. This began its life as an FHF ebauche, but it has a modified setting bridge and custom setting bits--so the usual FHF setting patent is not stamped on it. Noting it, as it explains why the setting bits shown in later movement catalogs (1939, etc.) are different: they reflect a modified/custom version of the "new" FHF setting works patented in late 1926. I doubt this caliber was actually in use past 1926, but Gruen was apparently still buying movements & parts to provide factory repairs.
