Hello Paul,a possible answer could be 133 Gruppo Aerosulanti, (with 174a and 175a Sqn.) based in Bengasi,Lybia. Gruppo meaning Group and Aerosulanti meaning Torpedo-Bombers (would fit the badge symbol). They flew S.M.79 and the motto La Nobile means The Nobleman. I have included a website giving some info on the Italian Air Force of 2ndWW. Hoping the IAF did not recreate a 133 Sqn. post-war.
Hope it helps.
Jo
