Recently we tried to disassemble a James, but this led to a disaster. The entire upper body was irremovable and we could not access the chassis. A screw was inaccessible as part of the body mold had covered it up!
Is this on all the models, or just ours?
i think its all, because i tried to disassemble my James a while ago and had the same issue.
I managed to get it loose on mine. It did take some doing, though.
