I introuce you my 1st treasure, my 1/250 IJN Musashi. I bought this kit at the end of 2002 and this kit is pretty good one. I spent about 1 year building it.
It (ARII Musashi) has a better shape than the 1/350 kit, but getting photoetch for it is pretty hard; so I made it without any PE.
I used stretched sprue, plastic plate and square plastic beams and easy-bending thin wire to add detail.
It is hard to get Musashi details on the web, so I copied parts off Yamato models on the web. I didn't consider the difference with between Musashi and Yamato, but my model's shape is pretty complex and seems nice. I'm satisfied with my model.
