I got a 3rd Rail 3 rail engine and the seller described the marker lights as missing. I could see the bulbs in the pics so I figured he meant the actual housings. They also were right there in the pics, just not where I'd expect them to be.
It appears that on this older model of a PRR N1 2-10-2, they are down low on the pilot. Not where I would have looked, not the seller either.
Now to see what this board is?
Rich Battista shared this pic from the internet and I spied them.
