I believe it is 1935 as 36 Temperature gauge is Electric if my memory serves me correctly ALSO I believe the openings for both would have a "bevel" inward if they were 36 as well. The face color is quite different. 35 earliest, 36 latest
I don't know...I had one of those very same gauges a few years back. Whilst it resembles 35-36, it will not fit into a 35-36 dashboard, because the sides of the housing protrude outwards too much and prevent fitting of the speedo.
I thought maybe German Ford truck?
