Mike LaForestKeystone Howard, Series 9
Shugarts book has 2 entries for Series 9 (checkerboard DMK) movements. One states 3 position and the other 5 position. I have never seen one marked 3 position, OR 5 position. They all seem to be marked "adjusted" only . 5 position watches are evidently RR grade; 3 position watches are not identified RR grade. So, how does one tell if it is 3 or 5 positions? Maybe someone has a picture they can post of Series 9 movement marked, "adjusted five positions".

Bob MurrayMike-
The ATSF rules for 1938 accepted all 16s Howards of 19, 21, or 23 jewels for their service.
Regards,
Bob

Mike LaForestThanks, Bob. I saw that in the early pages of Shugarts book, but judging from their serial numbers, most of these movements are in the 1903 - 1910 era, so I presumed RR
grade standards would be more forgiving in those years.
