Pan American 34B Trumpet!

Description

I will be the first to let y’all know I do not know anything about this trumpet. I did some Internet sleuthing, but could not come up with an exact match.
Hoping someone who is more knowledgeable will send me a note to be able to provide more details on the year is manufactured and the model number.
This would help me determine a fair value, so I’m putting it up for auction as a starting point.
Looking forward to hearing from somebody.
