A very definite no to that question.
A date of manufacturer would not be very meaningful as many leftover parts from prior years were used. For example, I have a 152 that I am restoring. Looking in the Greenberg new O gauge book, I see that the coupler mounting style was last used in 1917. The motor type was first used in 1918. Most likely that was made in 1918 using a frame left over from 1917.
