Hello Shinpachi san, It can only be said that your great work represents a labor of love. Your love of your subject matter. In a sense, you are rebuilding something that was lost. As I recall, many of the instructions for building these great planes were lost, destroyed by the very industry that created them. In your way, you are recreating that lost history. I think your detailed rebuild of these planes should be made available to the world. Perhaps something of them could be sent to a museum of aviation history? Just a thought...
