SJWi, those are all excellent kits (assuming that the HE-51 is the Hasegawa kit) I have always been a big fan of the 1930's "Age of Transition" aircraft. I'm still working through my air-combat rules for the period, they have made it to the Beta version. If you are interested you can find them under the "My Own Rules and other wacky ideas " tab on my blog. I originally started doing aircraft for the Nomohan Incident but things rapidly got out of control and I now possess aircraft for most major and many smaller air forces of the 1930's
