Apologies for the Deuber typo. According to the database, there were only around 1200 of this variation, and only around 6000 of the grade, so I'm not surprised that my search is proving to be interesting. I didn't think it was railroad grade, and I'm fairly certain the watch case isn't original to the watch. I've found pics of serial numbered watches close to mine, and the movements are similar but not exact. I will try to send along better pics.
