It is a loco I have wanted for many years. I do have an unmade kit for the loco but initially thought to buy this. However, I won't. The loco entered service in June 35. Almost exactly a year later, she was fitted with the 40 element domed boiler but because of initial teething problems with the reverse turbine and 4 visits to the works, she was in the shed for nearly half. With the removal of the discount as well, I shall probably build the K's kit into the version which was the longest lived and can be run alongside the Coronation loco's as she had the domed boiler a year before they entered service.
