Blessing Artist B88 F Attachment Trombone with case and mouthpiece. Made in USA.
See pictures item has been used and has wear on its finish. Slide goes back and forth and the valve also appears to work.
I am not an artist and do not know enough to tell you anything but these basic things appear to work.
Serial number on slide matches number on main body.
More than likely this item will need some reconditioning!
Case is included but is in bad shape
