Thank you for looking. Based on the serial number, it is believed to be from 1977. It is said to be one of the last models before the factory closed in 1979, meaning it's from the final period when Olds took pride in crafting their instruments. The nickel silver plating shows many small signs of peeling. There are no major dents. All pistons and slides are functional. While I do not have the skill to play it myself, a friend with wind instrument experience tried it and said, "It can be played properly." Accessories include a mouthpiece and the original case. The exterior of the case has significant peeling, and one of the clasps has fallen off. There are many sticker marks. It will be sufficiently protected for shipping, so I will wrap it in bubble wrap and stretch film.
