Circa 1910 this one is identical to the red plate version, except it has a black plate.

Early smooth boiler, but has later motor and automatic coupler.

The above variation is circa 1911 as it has 10-spoke wheels, black etched plate, boiler piping, hook coupler and handrails with cast in stanchions (cotter pins). It also has 1911 stamped on motor plate.

Circa 1914 with auto coupler, "straight rod" valve gear, cotter pin stanctions, rubber stamped lettering

The locomotive above has a 1918 date on the motor plate, could be someone switched motors or that Ives just used some leftover castings.
