My vote goes to the Breda Ba.65
"The embarassing superiority of the C.R.32quater over its supposedly more modern monoplane contemporary was underlined on August 4, 1940. At 5 p.m. that day, six Ba.65s of the 159a Squadriglia, led by Capitano Dell'Oro, attacked British vehicles at Bir Taib el Esem, while six Fiat C.R.32s of the 160a Squadriglia, led by Fanali, waited 3,000 feet above to follow up their strike. The Bredas were about to make their third and last strafing run when they encountered a Westland Lysander of No. 208 Squadron, escorted by four Gloster Gladiator biplane fighters of No. 80 Squadron, flown by Flight Lt. Marmaduke T. St.J. Pattle, Flying Officers Peter G. Wykeham-Barnes and John Lancaster and Sergeant Rew. The Gladiators promptly attacked the Bredas, Pattle and Wykeham-Barnes downing two of them. At that point, however, the C.R.32s dove on the British fighters, claiming three of the Gladiators. The fourth Gladiator, flown by Lancaster, was damaged but returned to its base. Pattle actually escaped the C.R.32s only to encounter three more Bredas and 12 Fiat C.R.42s, the latter of which shot him down after a 15-minute fight."
Rescued from gladiators and westland lysanders by cr32's . I think we have a weiner .
