Circa 1909-10 with smooth boiler casting and red plates.

rivet detail on boiler probably 1911 Note still using red plates, the one below is identical except it now has the black plates.

Similar No. 4, this one has a 1912 date on the motor, normally we think of the 0-4-0 version has coming from 1912, but it could be that Ives sold both that year or that the No. 4 was available after 1912.
