Three SCAL types were flown. The FB.20 was a
monoplane from about 1936 but beyond that nothing further is known. The
FB.30/31 was a pusher, twin boom, two seat touring aircraft: three built, with different engines. The
FB.40/1 was a side-by-side seat
biplane trainer. Two different engines were available pre-war and other engines were used post-war. ==References==
