I'm afraid that rule only applies to French A/C. On Britmodeller they're positing that the flood of Camels is meant to make up the shortfall from the Felixstowes--everyone saw the incredible builds and rushed out to buy . . . the Roden kits. You'd think a Spad XIII would be a license to print money, but Sir Peter remains a Francophobe.
Not sure that is totally fair...
1. WNW originally stated they did not want to do kits where there is already a decent kit existing and available in 1/32 - given there are existing kits of the N11, N16, N17, N23, N27, N28, Spad 7 and Spad 13 in 1/32.... That said, due to pressure from fans, they did do a Camel, so who knows maybe in the future we will see some of these French subjects but its clear that initially those were not subjects WNW was going to consider....
2. Salmson 2A2....
