See photos for condition- some dings and finish loss.
Slide seems to move okay-may need some lubrication. Appears to be a fluted slide? Appears to be 68-69 by serial number.
Case is in good condition with some signs of use but no cracks and latches, handle and hinges are all intact.
Not a trombone player so hopefully this is accurate- Be glad to answer any questions that I can.
