Hey, thank you very much for taking the time to point this out! As embarrassing as it is, I have to admit that you are entirely right! It's funny, because I spent quite some time on modelling the plane, and I had done a version of the Model 10 in paper before (which, in fact, WAS the correct model).
I must have accidentally confused the schematics when I started modelling this item, and never checked back with the reference material.
So, yes, this is The L-049 Constellation. Good catch! I have updated the model name and description. And sorry for the confusion!
