Please Help Me Decipher Yamaha Flute Model YFL-471?

I would like to purchase a flute for my daughter--surprise Christmas present--so time is critical. But the model number is Yamaha YFL-471 HAL. I know what the "471" means, and the "H" signifies B foot. What about the "AL?" Can anyone provide some insight? Also, is this a good step... show more I would like to purchase a flute for my daughter--surprise Christmas present--so time is critical. But the model number is Yamaha YFL-471 HAL.
