Graham, you are quite correct. Call it general idiocy on my part. If the client had constructed the slidebars from the etch, rather than the cast ones, I suspect this detail would have been catered for.
Probably from the cylinder centreline being higher than the wheel centres...The GA shows the internal chamfer on the bottom bar only.
Again it is hard to judge from the photos but it does look as though the front of the smokebox and door is overhanging the front frame drop too much, so the cut and shut would help. How does it look with the chimney in place?I've contacted the client, who has given the go-ahead for a cut-and-shut to move the smokebox back. I'll not perform surgery just yet, as I wait to see what Laurie says first.

Again perspectives can be deceiving but from an engineering point of view I would have expected them to line up.The centre hole in the top of the smokebox is shifted forward of the steam pipe holes on the running plate.
Time to count rivets...Oh dear. Have I opened a king size can of worms?
