Welcome to the Between the Wars Group Build!
This GB encompasses aircraft in operation (civil or military) during the years 1919 to 1939 (inclusive). So, WWI types in post-war guise count, as do early WW2 types in pre-war guise. Although worthy of their own GB, Spanish Civil War contestants are eligible, too.
Standard GB eligibility rules apply: builds must be no more than 25% complete upon entry, and must be of an applicable LSP subject.
Let the games begin!
