Worth adding to this thread. A Gem PRR F3 mogul brass screwdriver kit that was originally painted for GN but later repainted for PRR. It has been updated with a modern era headlight and generator over the oil headlight from the factory model and also has a reverse light on the tender. I need to verify that was remotely prototypical for PRR, but for now I like it just how it is sans a repaint of the boiler face to make it fully PRR. While this class never had them, a Keystone number board would be kind of fun.
Factory model with oil headlight:

Modernized version by a previous modeler. While the F3 was retired two decades prior to the era I primarily model for PRR, the updated headlight and generator give me a reason to bend the rules a bit and say a few of these perhaps lasted longer in my modeling world.

Interesting oddity in the GN painted boiler face. I'm assuming this was originally painted for GN and then repainted into PRR. GN was the other large road that adopted the Belpaire firebox, so this model could act as a stand in for a GN styled locomotive.

I like how the coal load is done on this tender.

Not perfect paint, but a nice little model that I can work on for future dual service like the prototype.
