That rod off the end of the crosshead slide has been put on 180 degrees out - it should point down not up; then the rod connecting it to the long rod from the valve control gear would be parallel to the ground not stuck up at a funny angle. Perhaps it was done deliberately to avoid having to dig a trench in the ground to accommodate it.
Yes, I spent some time looking at the pics and scratching my head on that one, I'd already noticed that the crosshead shaft had been cut but did not put the facts together. 😞
