Actually, You are still wrong Walter.
The Locomotive You have converted is the Philadelphia and Reading Railroad #408 http://www.northeast.railfan.net/images/pr408.jpg Part of the Reading Lines. That a photo of it from 1911. as you can see it is the same unit.
That locomotive was built around 1875-1880 and survived almost to WW2. I do not have the exact dates.
It was possibly later Painted to look like the MSTS Paint Job after 1924 when The P&R became known as the Reading Company.
