Glen, neither of the drawings in the Bowser catalogue show such a plate, but it may have been added by the person who remotored it. From the photo, yours appears to be closer to Arbour's "Sylvania Central 4-6-0. The side of the cab is exactly the same, and the window arrangement on the front cab wall also seems to be the same. While it's difficult to tell on the drawing, the class lights also seem to be the same 'tall' style, and the style of the domes is the same. The headlight, however, is the same as that in the drawing of their Sierra 4-6-0. To further complicate things, the boiler also appears to be from the Sierra model, as it has only one large-diameter section in front of the cab, then the taper, a small diameter boiler section, and then the smokebox. The Sylvania Central boiler has two large diameter boiler courses ahead of the cab, then the taper, a small-diameter course, and then the smokebox. It may have been kitbashed if it actually is from Arbour.
