Today, I offer up the American Flyer O gauge 3019 locomotive. This item was cataloged from 1923 to 1924 and appears to have been sold through 1925. It is simply a cheapened variation of the 3020 as it is an 0-4-0 engine (in most cases) as opposed to the 3020 that was a 4-4-4 engine.
The earliest version was likely painted black, as this color has been reported in the Greenberg's Guide to American Flyer O Gauge. I do not have a black 3019.
The 2nd version appears to be the dark green with red window trim, as shown below.
Then there is a later lighter green version with yellow windows. Mine is even more unusual in that it is a boxed item and came on a 3020 frame. This is a 1924 or possibly 1925 item (as the dark green lithographed Illini cars transitioned to a lighter green colored lithograph, apparently in 1925). Not sure as to why this 3019 cab ended up on a 3020 frame, but my guess would be either poor quality control, or simply a lack of 3019 frames and too many 3019 cabs.
The Greenbergs Guide lists a 3019 in brown, which would likely be a 1924 item. I do not have one of those.
As the Columbia cars transitioned from brown lithography to maroon lithography c. 1925, as evidenced by the brown Columbia cars not having an observation car and the maroon Columbia cars having observation cars, with 1925 being the first year that observation cars are cataloged, it would appear that the maroon 3020 and, if it exists, the maroon 3019 both date to 1925.
Here is the maroon 3020
And the maroon 3019 c. 1925
