Shimano trigger shifter (much better than gripshift - especially for kids, particularly if its cold / wet / muddy).
Proper metal kids-size brake levers (not plastic cheese so often found on some bike-shaped-toys targeting the kids market)
Good condition with only minor scuffs that show age - see pictures.
I personally gave it a couple of full services during our ownership (3-4 years) so everything is well greased and running smoothly.
Simply outgrown. Was loved so much, one of the boys insisted on getting a Wiggins Chartres 26 as a direct replacement.
