Let's see..Ju-52..pathetically slow underarmed german trimotor
transport/bomber
    PBY..again pathetically slow underarmed Navy patrol flying
boat.
    Halifax was a poor man's lancaster.
    He-115, another floatplane who's biggest claim to fame was
fishing downed pilots out of the Channel and praying that the
RAF was sound asleep.
    Ar-196, which would come in handy if we had any German
surface ships, and at least carried a pair of cannon.  Still duck
soup to virtually every fighter currently in the game.
    Horsa glider...big wooden box full of squishy things 
 
     This was off the top of my head, btw..I suppose getting a
reference book would probably be overkill.  All these birds have
some geewhiz value as niche items but not very useful.
