No, Invasion of Ethiopia 1935
Just for the record, no 109T was in Ethopia.   Savoia-Marchetti SM.79 and Savoia-Marchetti SM.81 bombers and Fiat CR-42 were your "best aircraft" the Regia Aeronautica (not the Germans) had.   
On to the Bf-109 T-2 and T-2/B
The three main differences were the arrester hook, catapult fittings and the addition of 1.18 meters of "wingspan".   The T-2's were technically similar to the E-7/N's (the T-2 had the DB601 N engine), except the wingspan increase Patin remote compass and special night flying lights (for the intended carrier landings).   T-2/B's had three attachment points on the ailerons, as opposed to the "standard" two for the Emils.   
Also, only 79 T-2's and T-2/B's were made in total.   They were then de-navalized (as someone else stated previously), sent to Norway, then on to assist in the BoB.
