Help me identify this horn ASAP!! (Pan-Am)

So I have a dilemma.. My mom is on the other side of the country in St. Louis at an old thrift store.. she said that she found an old Pan-Am Tenor being sold for 150$.. she says it looks in good condition (just a little bit rusty). I had her check the pads and she said that they all look pretty nice.. but she wants to know if it would be worth anything.. and to that I said

BULL! GET THAT HORN FOR ME! :twisted:

Well anyway.. the two serial's she provided are

1153489

and

P27648

Please respond ASAP.. because she is only going to be in St. Louis for one more day after today O_O

Thanks in advanced,
Action
