This group of pennants is listed in the Standard Catalog as type seven BF3s. But due to their size variation from other BF3s there is some controversy about their placement in the catalog. Several noted collectors think these pennants are rightly BF4s. Burdick,in his book, lists a slightly larger pennant that he calls a BF4. But this pennant cannot be found in any listing and as a result many rightly believe that the type seven BF3s are actually the missing type BF4s.
Below is the full known set.
