Well, I didn't go to York but the Postman did stop by today and left an interesting looking box for me. Buffy thought it might be for her.
This was inside and we all know good things come in that kind of box.
It appears I am collecting Atlas O SW8/9s.
So new(ish) (abt 20yrs old in the box?) I haven't even put the handrails on yet. Runs smooth as silk and as slow as a turtle. Looks like it has never been run before. I did have to diagnose (it would stop at the same exact spot on every track switch) a cold solder joint on one pickup wire but it's all good.
