F327

Late in life, the 327 was given an F-rotor movement.  The case was redesigned with a closed back and the spring-and-grommet system.  It might not have been much faster to build but it kept out dust better.  This model was only re-discovered in 2010 thanks to our friend, Tammy.  A few models from the Early Years were sold into 1935 so I would not be surprised to see an F727 or an F356 one day.
