Mike - you really seem to have your heart set on WW1 aircraft subject. Glad I'm not the moderator on this one as your interesting find about the Hanriot still is a tough decision. Even though built in Italy, it was a French design (maybe you can find an Italian name on the design team?). If Eric gives the green light on it that would mean the Stuka would be allowed in as it was license built in Italy.
Anyhow, as an option I remember finding a couple Ansaldo kits when we were mud deep in the Great War BG last year. Made by Karaya, here is a review:
