I just bought a trombone off the internet. Condition is unclear, but it was very cheap, so I am okay if it ends up as decoration

The seller didn't have any more information about it. All I know is from the pictures.
It is (mostly) silver plated with an engraving on the bell saying "ARTIST".
Due to this I would expect it to be American or British.
Looks like a small bell, bore and receiver.
Would be great if any of you have an idea of what it is.
Hope you can see the pictures!
As soon as I receive it (hopefully in the next days) it will be interesting to see how it plays.
Thanks everyone!
