Rare Vintage Alliance USA Trumpet Bb Silver Color With Case And 3 Mouthpieces

Description

Up for sale is this vintage Alliance trumpet.
I don't know much about the maker of this instrument. It is very hard to find any information about it.
This trumpet is in great shape. There is no major damage or dents.
There are only very few slight dings.
The vales move, but are stiff.
The slides are stuck in place. I didn't want to do any damage trying to unfreeze them.
The case has a decent amount of wear. However, the latches and handle are still functional.
It comes with the 3 pictured mouthpieces.
