Hello Nige,
Wonderful work, and my thanks personally for allowing us all the privilege to enjoy your meticulous work, and problem solving. This one will be a must follow along. Did this kit years (1980) ago in 1/48th (largest available, I do believe at the time), the old ESCI offering,and egad this Trumpy beast is Marvelous in comparison. This will be an education.
Best wishes....
