Even if not proved we assume Mickey was on both sides (functioning as an identity number it must have been visible from both sides!). Wingtips were in all probabillity yellow on top (see photographs provided in the linked site above).
I'll be glad to answer other spesific questions regarding this aircraft if needed.
Good luck with the model,
Kjetil
