I'm not extremely familiar with musical instruments, but this was found in a abandoned storage locker. I took it and had it serviced at a professional shop and the people there was able to give me a little bit of information about this particular item. After they serviced the trombone they said everything plays and works as it's supposed to. I believe they said it was from the late '60s and it does show some of its age. Some of the gold has discolored and there are small dents here and there. The hard case is in pretty good shape besides having some scuffs here and there. I will try to get more pictures of the case posted ASAP. As I said, the case does have some scuffs here and there but operates and funks and as it should. Although I do not have a key for it. Please ask any questions before bidding if you are unsure about something. Thanks for looking
