One of these days I'm going to build one of them as one of the 2 'prototypes' carried aboard the Soryu at Midway. I got interested in building an example after reading "Shattered Sword" by Parsall & Tulley. They mentioned two Judy's being carried for long range reconnaisance, but one was somehow damaged during some manuvers by the carrier (maybe avoiding attack ? - I can't remember). And I'm not sure if the other ever took off, but I believe it went down with the ship.
Anway, I thought it would be kind of cool to build one with the markings of the Soryu.
