Monktonhall Place

Leaving no stone unturned. Back to get what I think is the 2nd last one of the Musselburgh / railway bridges find. But I'm never too sure; every time I go, I still find myself scouring the walls, the barriers, the parapets. There's a Mate or two on the bridge itself, but after close examination I can't find any more there. 

And with that? It was off up the A9 to its end.
