IIRC the C1 was a standard body with the super wing and tail (fuel tank?) so not quite standard, more standard+
Thats why the K2's were retired as their older (hard) wing meant that more (different) spares were required and that the flightcrew could not be cross certified between those with standard wings and those with super wings (Beags will now leap in and correct me)
You get the gist.
