Al sent me this scan of some info from Smith Metal Works. I have to file this under "you learn something new every day." I have never seen one of these up close but from every angle, this is one nice accessory.
With that 1912 pulling out of it, I do have a much better idea of size.
I think I am going to give Bob Thon a call to find out more about this.
I know if I had one of these I would have to modify it a little. I like all of my structures lit. I'd also have to find some signals that match this to make sure inbound and outbound freights don't collide....
