Y’all ain’t ever see a clarinet like this before

My name is Colin and I’ve been playing Clarinet for a little less than 5 years. About 3 years ago my Great Aunt, a former music teacher, sent me this Clarinet in the hopes of me playing it someday. As soon as I saw it and showed it to my teacher he deemed it practically unplayable, leading me to leave it in my closet for 2 years! I found it today however, and wanted to show it off and maybe gain some extra information on it!
