There´s no doubt that by the time Lesney designed the K-26, they had realised that it was purely a toy for under 10s and that there was no extra sales to be gleaned to design in any adult collector appeal.
Although I have no specific memories, the chances are that a fullsize version of the K13 passed me in the street many times during my childhood, and as such this toy still has great appeal to full grown collectors........
although always a toy, the late 70’s kings were definitely childlike.
the superfast change over used the same reasoning, built for children and not adults.
that's one reason why the y series took off in the 70’s and 80’s and also the series i most enjoy.
the newer models (2000's) that are shown in other posts are very nice and have an adult appeal to them.
