Quite welcome!
I like digging into the books for things like this. The link to the original article has the standard PRR lettering before they went to the ball keystone emblem that's most common (those photos are in the public domain online in the Hagley Library PRR collection)... but it lasted until 1952 which in the era of steamers and high sulfur coal makes it likely to have been repainted at some time just to keep it from rusting away.
